Driveway Width – How Wide Should My Driveway Be?

Driveway Width

Selecting the appropriate driveway width is vital for any property, accommodating various vehicle sizes while ensuring seamless navigation and protection of surrounding structures and landscapes.

The typical driveway width is between 10 and 12 feet, suitable for small vehicles like cars. For larger vehicles such as vans, trucks, or RVs, a minimum width of 12 feet is recommended to prevent damage to the vehicle and nearby structures. This width ensures sufficient space for parking and maneuvering without impacting nearby landscaping or building features.

Continue reading to discover additional factors that influence driveway width, including property layout, safety, and aesthetic considerations, for an optimal driveway design.

Driveway Width According to the Number of Vehicles

There are standard driveway widths for the number of cars you will park. For example, if you have more than 1 car, it is wise to know the recommended width for a driveway to accommodate all cars comfortably. Let us have a look at these measurements. 

Single Car Driveway Width

A single-car driveway refers to residential driveways, and in this case, the above-mentioned standard width size of 10 feet to 12 feet will be appropriate and enough. However, you must ensure that you leave enough space on both sides of the driveway so the vehicle can turn easily without damaging any walls, fixtures, or plantations. 

Plus, there should be enough space for you to step out of the car and onto the driveway’s pavement and not into your lawn. In case your driveway has walls on both sides, you have to ensure that there is enough space for both your car doors to open without hitting either wall. 

Two-Car Driveway Width

A driveway width for a single car

The minimum recommended width for a 2-car driveway is between 20 feet and 24 feet. 20 feet will give you enough to part two cards next to each other. However, this width will not allow both car doors to open when parked side by side. 

On the other hand, a 24 feet wide two-car drive provides ample space for both cars to park next to each other with their doors wide open. 

Three-Car Driveway Width

As the name suggests, a three-car driveway, also known as triple driveway, allows you to park 3 cars or small to normal sized cars in a parking space. The minimum recommended measurement for this type of car driveway is between 20 feet and 30 feet. 

Once again, the wider the driveway, the better it is. You have to make sure that you can open car doors easily of all 3 cars parked together on the driveway. 

Circular Driveway Width

A circular driveway refers to a round-shaped drive or one that resembles a horseshoe design. If you are planning to build a circular driveway on your property, the minimum width of this driveway must be 12 feet. 

This will give each vehicle enough space to turn without driving into the wall’s edge and causing damage to your driveway, property, and the vehicle itself. 

Different Turning Radiuses

A turning radius is a minimum area required by the vehicle to make a turn without touching or damaging any walls, pavements, edges, plantations, lawn area, etc. there are four main turning radiuses you must consider when designing a driveway and determining its width. 

Parking Areas

The minimum recommended turning radius for your parking area should be 9 feet to 18 feet for a single car.  However, you will need an expert’s opinion on this if you are planning to park more than one car. On top of that, does your family or business have cars and vehicles of all shapes and sizes? 

In that case, you will have to follow a thumb rule and create a turning radius for the parking area, keeping the largest vehicle or car in mind as smaller vehicles. As far as the bigger automotive can navigate, smaller ones will have no issue at all.

Backout Area

A parking space requires a minimum of 30 feet to 35 feet in length and 10 feet in width. However, a typical turnaround dimension of 10 feet by 20 feet should provide enough space for your car to back into or pull out of the drive. 

Driveway Entry Radius

You must allow a minimum of 10 feet to 15 feet at the entrance of your driveway in order to avoid parking on a sidewalk. These sidewalks are the property of local and state governments. Therefore, you must not park your car in the way of people walking on these sidewalks.

Garage Turning Radius

This turning radius will vary with the size of your garage, i.e., how many cars/vehicles you will be parking in it. That said, here is a minimum breakup of radii for different garage sizes. 

  • A single car garage- 9 to 12 feet in width
  • A double car garage –20 to 24 feet in width
  • Parking stalls –  10 x 20 feet
  • Single car turnaround – 10 x 20 feet

Things You Must Consider When Designing a Driveway

Here are seven factors that you must think through when planning your driveway. 

  • Pick a style that allows you to utilize maximum parking space
  • Always make sure the ease of access 
  • Do not forget about the driveway accessories such as LED lights and curb lights. 
  • Pick a design that matches your taste, i.e., contemporary or traditional
  • Check with your local authorities if you need permission before installing a new driveway
  • Do not forget the importance of drainage 
  • Take care of the trees and other plantations nearby that may get under your driveway and impact its structural integrity. 

FAQs about Driveway Width

Here are some frequently asked questions about driveway width to help guide your planning.

How wide is a typical driveway?

The width of a typical driveway usually ranges between 10 to 12 feet for a single-car driveway. This width comfortably accommodates most standard-sized cars, allowing enough space for drivers and passengers to get in and out of the vehicle without constraints.

How big is an 18-car driveway?

An 18-car driveway, designed to hold 18 vehicles, is a substantial undertaking. The size would significantly depend on how the cars are arranged – single file, double file, or in a parking lot style. Typically, each car requires a width of about 8 to 10 feet and a length of 18 to 20 feet, leading to a very large area for 18 cars.

What is the ideal size of a driveway?

The ideal size of a driveway depends on the number and type of vehicles it needs to accommodate. For single-car driveways, a width of 10-12 feet is standard, while a double-car driveway typically measures between 20-24 feet wide. The length should ideally be at least 18-20 feet to comfortably fit most cars. For households with larger vehicles or multiple cars, adjustments in width and length might be necessary for convenience and safety.

Conclusion

Now that you know the basics of driveway width, you can use this information to plan the design phase of your project. However, if you wish to get some expert advice, Paving Finder can help you connect with experts’ opinions and access additional tips and resources.

Macadam Driveway – Cost, Maintenance, Pros and Cons.

driveway

Many property owners prefer to have macadam driveway installed for their residential and commercial properties since it is economical and offers a smooth, sturdy, and esthetically pleasing surface for all types of automobile traffic. 

It is a common fact that surfaces laid with this paving material are usually hard-wearing, smooth and will enhance the appearance of your property exterior. Since macadam is skid resistant, like asphalt, it guarantees the safety of vehicles plying on it, particularly, during the winter. 

But what is a macadam driveway?

Macadam driveway, also referred to as chip and seal, tar and chip, and oil and stone, is a type of road construction where single-sized crushed stone strata of small angular stones are put in skin-deep lifts and compressed extensively. The compaction may result in the formation of a binding coating of stone dust (source material crushed stone) and may also be coated with a binder after rolling to bind stone and dust together then compressing the stones into the sticky material to create a firm, lifelong surface.

A macadam pavement, unlike asphalt, requires less upkeep as it does not need to be sealed every year.

Although the macadam construction method has mostly been supplanted by asphalt and concrete on public roadways, lots of homeowners still yearn for the unique smoothness and esthetic of macadam. This type of driveway surface is praised for its esthetics, minimal maintenance needs, and cost: it is somewhat less expensive to install than asphalt.

The worker was busy installing the macadam driveway.

How much does a macadam driveway cost?

Although installing a driveway, using macadam is generally inexpensive to build, several variables may increase the cost to a substantial amount of dollars. One common factor here is municipal regulation; since a driveway links to a public roadway, there may be local laws limiting the width of the driveway and the materials used to construct it. A permit is usually required, and the prices can range from minimal to expensive, depending on the region.

Notwithstanding, resurfacing an existing driveway with macadam can cost about $600 to $1,800 for a 12’x50′ (single-car driveway), or $1 to $3 or more per square foot; and laying a new driveway (particularly with a gravel foundation) can take up to $1,200 to $2,400 for a 12’x50′ (600 square feet), or $2 to $4 or more per square foot. However, the amount of work required to create the base, as well as the quality and quantity of stone utilized in the top layer, can drive up costs.

It is also worth mentioning that driveway contractors don’t usually charge by the square foot; instead, they offer a total price for a given project, and large projects may qualify for discounts.

How hard is it to maintain a macadam driveway?

Maintaining a macadam pavement is not difficult. It conceals oil spills better than asphalt and concrete driveways, and it’s beautiful finish lasts even if it is not treated on a regular basis.

Furthermore, a macadam pavement does not need frequent seal coating, which is often performed every two or three years on asphalt driveways. The only work you’d have to perform would be to repair or replace macadam that have been dislodged from the asphalt.

What are the pros and cons of a macadam driveway?

Driveway built with macadam material comes with some advantages and disadvantages; however, your choice of opting for this surfacing material is dependent on how you weigh its pros and cons. The below advantages and drawbacks of this driveway type will help guide your decision for your next paving project:

Pros:

  • Maintenance and repair: Macadam driveway requires minimal maintenance. It does not require to be sealed as often as asphalt, and even tiny cracks tend to mend on their own. Notwithstanding, you may refresh the surface every 10 years or so by applying extra loose stone and hot bitumen.

    In addition, care should be taken when using a snow plow to remove snow from this pavement surface since the pressure from snow plows can scratch the rough surface of macadam pavement. So, if you’re going to use a plow, keep the blade just above the surface; otherwise, use a snow blower or shovel as a best alternative.
  • Ease of installation: One of the most appealing advantages of a macadam driveway is how easy it is to install. The gravel base is the first step in the procedure. Following that, heated liquid asphalt is poured over the gravel then loose stone chips are put over the liquid asphalt and compacted.

A macadam pavement, like a tarmac driveway, can be constructed in a single day and you may walk on it right away after installation. However, it is recommended that you wait at least three days before driving or parking on your new macadam paved driveway.

  • Design choices: This sort of paving material comes with a variety of design options. The color of a macadam pavement is determined by the top layer of loose stones, and there are many distinct colors to select from. Certainly, you can use this sort of material to construct a one-of-a-kind and visually stunning driveway.
  • Comfort and convenience: Macadam driveway is a fantastic choice if you desire a slip-resistant surface. Its rough surface improves grip and reduces the danger of slip-and-fall incidents, notably when the surface is covered with snow or wet.
  • Cost-effective: Compared to concrete and asphalt driveways, this type of driveway is less expensive. It’s a good option if you have a lengthy driveway since it’s affordable.

Cons:

The main disadvantage of installing a macadam driveway is that not many driveway paving companies provide this service.  Besides, a driveway paved with macadam has a short lifespan; whereas concrete driveways may last up to 40 to 50 years with little repair needs, a driveway built with macadam will only last for 10 to 15 years at most. Furthermore, since this type of driveway surface is rough, removing snow off it might be difficult.

Is a Macadam driveway right for you?

If you’re looking for a casual paving material that’s also affordable, macadam could be the ideal option for you. Notwithstanding, some cities and suburbs may have regulations or agreements prohibiting the use of this informal material for all roadway construction; hence, it is advised you check with your local regulations.

Conclusion

If you want to keep your budget modest and want an easy-to-build driveway, a macadam driveway is your best bet. Although it may have a limited lifespan than a concrete road; however, given the expense of installation and maintenance, it is definitely a cost-effective alternative for all homeowners. Therefore, if you are considering having this type of driveway installed for your residence or commercial settings, think of it as a very good choice!

Concrete Driveway Thickness – What is Your Best Option?

Concrete Driveway Thickness

You might believe that concrete driveway thickness in residential and commercial settings is roughly the same. After all, they all appear to be the same and can withstand the weight of automobiles, right? Nevertheless, the degree of concrete thickness we choose when constructing a concrete driveway can significantly impact the driveway’s long-term condition.

Cracking is a common problem in driveways, especially those constructed with concrete. So, to prevent this, ensure that the concrete is of uniform thickness. Besides, your contractor will most likely ask you a few questions to determine the thickness of your concrete.

So, what is the best concrete driveway thickness?

In terms of thickness, a minimum of 4 inches is the standard requirement for passenger car driveways. However, for heavier automobiles, it is recommended to increase the thickness from 4 inches to 5 inches. According to the Tennessee Concrete Association, this adjustment will add about 20 percent to your concrete price but will increase your driveway’s load-carrying capacity by almost 50 percent. 

For adequate drainage, the driveway should be sloped a minimum of 1%, or 1/8 inch per sq, towards the street to prevent water from stagnating on the driveway.

Even though many municipalities have enacted codes requiring a specified minimum thickness, the absolute amount may be larger than that needed by the code in some situations.  As a result, before choosing concrete driveway thickness while creating the slab, a concrete contractor ought to consider several factors.

 So, what factors should you consider when choosing driveway thickness?

Constructing a new concrete driveway is a time-consuming task that also necessitates some pre-planning preparations. The success of the final driveway depends on determining the required concrete thickness before delivery and placing any prepared concrete. 

Your driveway may well not be able to handle the load and pressure exerted on it if you misjudge concrete thickness by pouring insufficiently prepared concrete. On the other hand,  if the concrete is overly thick, it could result in an unappealing driveway as well as more money spent on the delivery than required. So, the following are the factors to consider before choosing driveway thickness:

Soil condition

When determining the thickness of the concrete to be used for your driveway project, consider the stability of the underlying soil since unstable soil necessitates more reinforcement. If you are unsure whether or not the ground is solid enough to handle the ready-mix concrete once it has dried and hardened, we recommend consulting a professional for help. 

Perhaps you go through with the project despite the fact that the soil beneath it is unstable; it may not be able to resist the weather conditions in your area for long. In a nutshell, ensure you seek expert advice regarding your soil type before proceeding with the project.

The driveway’s function

The purpose of the driveway has a significant impact on how a concrete driveway thickness should be. A 3″ to 4″ thick pad is sufficient for lightweight automobiles, but a forklift, RV, or dump truck are heavyweights and need a thicker slab. However,  you should not be concerned about intermittent delivery trucks using the driveway since they are not usually wholly laden. 

Notwithstanding, many professional contractors choose to build residential concrete driveways between 4,” and 6″ thick on a prepared base since thicker concrete provides more strength.

Budget

The impact on the budget is determined by the driveway’s preparation work, dimensions, and concrete thickness. For instance, the cost of installing four full-sized car garage driveways will vary significantly from the cost of constructing a parking pad that accommodates a small motorcycle or compact car. 

In addition, the thickness of the pour, the use of rebar, the addition of a compacted base and subbase, as well as the type of color additives, finish, and texture will all affect the budget.

Should I use concrete for my driveway?

The simple answer is YES! For a good reason, concrete is a popular choice for constructing driveways as its slabs are incredibly sturdy and long-lasting, and they need very little upkeep. So, it would not be a bad idea if you consider using concrete for your next driveway project in both residential and commercial settings. The following are a few advantages and disadvantages of a concrete driveway to help you decide whether or not to opt for it 

Pros

  • Affordability: When it comes to cost, concrete is a reasonably inexpensive alternative to consider. With concrete, you may only be requiring work done on your driveway just once during the period you own your house. Notwithstanding, concrete driveway thickness requirements can influence the cost.
  • Durability: concrete is a very long-lasting material. A concrete slab can endure 50 years or more if properly built and maintained.
  • Load-bearing capacity: concrete is an inflexible, strong material that can withstand even the heaviest vehicles when properly installed with the appropriate base and reinforcement.
  • Eco-friendly: Concrete driveways have lower embodied energy costs, making them a more environmentally sustainable paving option. That is, both producing and placing concrete uses less energy altogether.
  • Low maintenance: concrete driveways require little to no maintenance, which helps to save both money and time over time. It can last indefinitely, and no weeds will develop on the paved surface.
  • Heat reflectance: concrete driveways are cooler than their asphalt counterparts as they absorb fewer UV rays. They reflect the sun’s heat and do not significantly warm the air. If you want to appreciate the concrete reaction to the sun’s heat, consider walking barefoot on both asphalt and concrete surfaces on a hot day.

Cons

  • Unappealing: Concrete is not the most appealing construction material, even though color embossing and stamping are feasible. However, opting for such decorative treatment will necessitate additional upkeep and do not often last as plain concrete.
  • Difficult to repair: concrete driveway requires removing and replacing the entire concrete area during repair, which is hard to carry out. Besides, vehicle oil and fluid leaks can leave stains that are hard to eliminate.
  • It is labor-intensive to instal: for huge projects, a concrete driveway is not a very do-it-yourself-friendly material. Because pouring a concrete driveway requires a lot of hard work, most people choose to hire a professional to do it. However, the concrete driveway thickness can add to the labor needs.
  • It may crack with time: concrete, like asphalt, can crack with age. Nevertheless, this issue may be prevented if the concrete driveway is constructed by a professional contractor who strictly follows all necessary procedures.

Do you need rebar or wire in a concrete driveway?

Homeowners want to ensure their driveway is thick enough to avoid cracking, but there is another factor to consider. Concrete has a low tensile strength despite its compressive strength, rendering it susceptible to expanding over time, which leads to cracking. 

However, the concrete thickness can not be used to increase its tensile strength. Consequently, another material (either wire or rebar) will be used to reinforce the concrete. 

For residential areas with lower thickness and strength requirements, wire is more commonly used than rebar. In contrast, rebar is often an excellent option to consider for thicker driveways and areas with a lot of traffic.

Conclusion

Some factors determine concrete driveway thickness; however, most concrete driveways in residential settings are 4″ thick 3,000 to 4,000 per square inches concrete slabs on a 4″ to 8″ prepared and compressed gravel base. Nevertheless, it is wise to consult with an expert contractor when determining the actual thickness that would be best for your driveway project.

25 Best Driveway Alarms – The Ultimate Buying Guide

Driveway Alarms

Good-quality driveway alarms can make it easier for you to secure your house, business, or other property. But a driveway alarm isn’t only about security. It can also give you advanced warning of an incoming parcel delivery or visiting family members

What Makes the Best Driveway Alarm?

The best driveway alarm have two main parts: a transmitter that you position at the entrance of your property and a receiver that alerts you of a visitor. The ideal system will be able to detect movement, heat, or, ideally, both. It’s also important that the driveway alarm has a reasonable wireless range so that you have enough warning to react. Lastly, it should be possible to add more sensors and transmitters to ensure adequate coverage. 

The most reliable driveway alarm have sensors that work in one of two ways:

  • Electromagnetic or probe sensors: These sensors are triggered when large metal objects pass in front of them. So, if you only want to detect cars coming in or out of your premises, they’ll do exactly that.
  • Passive infrared (PIR) sensors: Can detect motion and heat, so the sensor sends an alert when a person or animal passes in front of it, and it can also pick up the movement from a car. 

Most driveway alarm sensors are powered by rechargeable or non-rechargeable batteries. Rechargeable batteries can be charged by solar power or by connecting them to an electric outlet.

How much does it cost to pave a driveway? (Pricing Guide)

If your existing driveway has lost its curb appeal and you are planning to repave it or install a new one, you would want to know the cost that will get the job done successfully. A new driveway will make your entryway more appealing, improve winter management, as well as add value to your home. 

However, as much as you seek to know the exact cost, it is also wise to understand that many factors influence how much you will pay to have your new driveway installed or repaving an existing one.

Driveway

So, how much does it cost to pave a driveway?

The first thing you are to look at when determining the cost for a new driveway is the material options. There are different materials available, including asphalt, gravel, brick pavers, concrete, tar & chip, etc. However, if you need the most cost-effective, hardest, cleanest surface material, then consider asphalt. 

With that said, you should expect to pay up to $3 to $4/SF for asphalt paving, on average. Nevertheless, this price typically depends on the project’s scope; like the quality, slopes, the topography of your house, curves, etc. 

For concrete and stamped concrete, you should expect to spend about $6 to $7 per square foot and $8 to $12 per square foot respectively. Besides, if stamped concrete is to be used for more complex projects, then expect to pay up to $18 per square foot. 

Brick pavers are another good choice, but it typically costs about $17 to $20 per square foot for installation. 

Asphalt can offer you a highly durable and robust driveway for a decent cost (although lots of homeowners do not like the way it looks). Besides, if you need a more colored and decorative driveway, then stamped asphalt is an ideal alternative, but the cost will be more significant. 

Concrete, the most common driveway material, is long-lasting and requires low maintenance. Plain concrete might be inexpensive, but it will cost more if you want it embossed and colored. The aforementioned highlights partly answer the obvious question, how much does it cost to pave a driveway. 

Additionally, since a concrete driveway might crack if constructed improperly, it’s worth spending a little more to hire a competent contractor. 

Brick pavers are also a high-end paving choice for driveways, although the labor expenditures are relatively significant since they are installed by hand. However, they are a good choice of investment as they will give your home an awe – inspiring entry that will endure a lifetime.

While the prices mentioned above are a basic reference to the types of expenditures involved, your particular project may include other factors that can increase the entire cost. For instance, the condition of the place that you will be substituting with a driveway will have the greatest impact on the cost. 

So, if you’re digging up a garden, the soil will almost certainly have to be removed before it can be leveled and a driveway foundation built. Except you are resurfacing an old asphalt driveway, otherwise, you’ll have to scrape up and remove all of the existing material before proceeding with the project. 

How much does it cost to pave a driveway

What is the cost of a new driveway?

The primary costs associated with having a new driveway installed include the installation, maintenance, the cost of material, and other costs. However, your expenditures per square foot could vary from $3 to $20 based on whether you choose asphalt, brick pavers, plain or stamped concrete, etc. Other factors to consider include durability, esthetics, drainage, and others.

Durability

It is an obvious fact that everyone wants the most value for their investment. As such, you also want your driveway to last the test of time to get the best bang for your bucks. For the question, how much does it cost to pave a driveway, you need to understand that no matter the cost, it is worth the investment. Asphalt is a very durable material for surface paving, and if well installed and properly maintained, it can endure up to 25 years or even longer. 

For homeowners in the northeastern climates of the United States, asphalt is an excellent driveway material to consider. Concrete is not ideal in this type of climate as it is susceptible to cracking and heaving during the period of freezing temperatures of this area, and as a result, repairs can be challenging and repair costs can also be high. In addition, ice melting with salt can develop pits in concrete, leading to blotches throughout the driveway.

Aesthetics

When it comes to aesthetics, individual preference makes all the difference. Lots of people prefer asphalt over other driveway materials when considering beauty since it can be seal coated to offer a fresh look down the line. Although asphalt color schemes are confined to black and sometimes darker red, it is still the preferred choice for many homeowners. Furthermore, asphalt is better than concrete as it also conceals oil spills and stains from automobiles.

  • Price is dependent on looks

Yes, extra cost also comes with the way you want your driveway to look. If you want a special tint to be added to your asphalt driveway, either at the end (as a sealer) or during the mixing process, then expect to pay more on expenses.

Maintenance

Maintenance is another cost factor to consider when installing a new driveway. Although it does not directly address the question, how much does it cost to pave a driveway? 

You will always want to be on the lookout for cracks because even little hairline fractures can grow into big gaps and potholes if it’s not fixed on time. This can result in more problems that will require huge expenses. 

In addition, driveways also require seal coating within six months to one year after installation, then every one or two years thereafter, depending on traffic volume. Although this increases the cost, it will improve the appearance of your home and also protect it from the elements such as water, oils, chemicals, and salt.

driveway paving cost

Other Costs

Regardless of whether you choose asphalt, concrete, or pavers, other costs may factor into the price of your new driveways, including drainage and material costs (as mentioned earlier).

Drainage

Drainage is also one of the factors that will help your driveway last longer. French drains can be constructed to redirect water away from your property if your driveway slopes toward it. Although uncommon, some areas have standards for how water from your home should be handled, including drains at the end of the driveway.

Material cost

The cost of the different driveway materials varied. Therefore, you will want to consider the material option that will cost less compared to the other options. In a nutshell, it all depends on your budget and what you are looking to get out of your project. But, how much does it cost to pave a driveway? As earlier highlighted, driveway installation costs are dependent on many factors; while asphalt is less expensive than concrete, it is as well more costly than gravel.

The difference between the concrete types

In the process of pouring concrete on your driveway, the contractor can add stains to the mix while it is still very wet. As a result, the concrete can be tinted to match the exterior or interior features of your home. Concrete can be embossed as well, which adds texture and patterns to the concrete, making it look like inlaid stone, marble, or even tile. These enhancements are what contributed to the pricing discrepancies.

Conclusion

Some factors influence the cost of installing a new driveway for your property. So, whether you choose asphalt, concrete, brick pavers, or even tar & chip, you should expect to get different price estimates from your contractor. However, rest assured that the benefits your home will get will be far more than whatever you spend on the project.

In addition, new driveway installation can increase the value of your property as well as improving its esthetic appeal. In all, ensure you hire a competent paving contractor to examine your property and recommend the driveway material that is perfect for your property.

Gravel Driveway on a Slope – 5 Steps for Success

Gravel Driveway on a Slope

A home built atop a hill may provide breathtaking vistas, but it also presents unique obstacles when it comes to landscaping the driveway.

Gravel is one of the simplest and most effective materials for paving surfaces that would support both foot and vehicle traffic because of its low cost and low maintenance needs. As a result, lots of homeowners and business owners alike make use of gravel driveways and pathways. 

Having a sloped driveway as a homeowner or business owner can be difficult to maintain, especially if you wish to use gravel. Gravel exhibits particular characteristics when it is used in a driveway, and having it on a slope can compound these concerns.

To some people, gravel can not be used to pave a sloping driveway due to its propensity to migrate, disperse, and shift. There may also be fears that the gravel can be washed downhill if it rains heavily.

However, if your question is whether gravel can be laid on a slope, then the answer is yes. At the same time, to mitigate the common problems known with gravel when used on a slope, all you have to do is use the right materials and install them correctly.

So, what are the ways to keep a gravel driveway on a slope?

Below are a few methods to keep gravel driveways on a slope

  1. Build a Gravel Base Layer
  2. Form a Crown to Your Gravel Roadway or Driveway
  3. Create Proper Drainage
  4. Use a Gravel Grid
  5. Control Gravel With a Border

Many of these techniques can be used together to build a long-lasting surface that is resistant to erosion, flooding, ruts, and slippage. This will save you a lot of time and effort when it comes to raking or re-grading gravel surfaces.

Gravel is not the best material for a slope, even a 1:12 slope, as specified by the ADA for wheelchair ramps. It is, however, still possible, especially if you use a grid to hold the foundation layer in place and use the appropriate gravel.

Driveways with gravel on a slope are shown on the image

Why is it difficult to have gravel driveways on a slope?

The truth is that gravel material moves with time, making it usually unfeasible for a driveway on a slope. Naturally, gravel will roll downhill when driven over, and also when it rains. If you don’t use stabilizers, it won’t stay put.

When gravel is spread in a typical manner on a sloping gravel driveway (that’s a gravel surface dressing applied right on top of the sub-base material), it can result in the following three issues:

Problem 1- Gravel migration

When gravel is spread straight on a slope without the use of a stabilizer, the gravel appears to migrate toward the base or lowest section of the slope after some time of use. This issue is particularly with gravel driveways or slopes which automobiles use regularly. 

As the gravel that’s migrated to the base of the driveway gets deeper and less stable, it becomes more difficult to drive or walk over. This deep section of gravel then migrates again across surrounding surfaces with increased pedestrian and vehicular traffic. The size and type of gravel utilized can exacerbate this migration. However, building a gravel driveway on a slope can still be accomplished.

A larger rounded pea or river gravel of 200mm will probably migrate much farther compared to smaller angular gravel of 10mm. As the loose gravel split out of the start of the slope or the entrance of the gravel driveway, the whole thing will start to look like a mess. This loose gravel is then either subsequently crushed under vehicle weight against the driveway, or ground into various surfaces, much like a tarmac road surface.

Problem 2 – Loss of surface gravel dressing

When gravel migrates, it leads to loss of gravel from the slope or driveway, exposing the sub-base material. So, if you want the surface to keep looking the way it should be, then more and more gravel ought to be placed and scattered over the surface to restore the lost gravel, and the round of gravel migration and loss begins again. This develops into a long-term maintenance problem that will recur. 

Problem 3 – Formation of ruts and potholes

Ruts and potholes can form in the sub-base due to a combination of gravel movement, exposure of the material sub-base, and loss of gravel. In addition, rainwater washing down the slope, especially in severe downpours, can begin to wash the foundation of the subsurface, including some of the smaller particles, contributing to the development of ruts and potholes. The problem worsens with time as vehicles continue to travel over the same areas of the sloping driveway.

This issue is peculiar to gravel driveways on a slope, and it can not be resolved by simply adding more gravel; instead, the potholes and ruts ought to be covered with even more sub-base material, re-graded, and compressed before placing the gravel surface dressing. This, however, does not solve the problem in the long run, since the same problem will repeat in the same spots on the hill.

Number of ways to keep gravel driveways on a slope

Although it seems impracticable to build a gravel driveway on a hill, still there are methods to adopt in order to construct a stabilized sloped driveway using gravel. 

Several of these techniques can be utilized together, to form a long-lasting surface that is resistant to ruts, erosion, slippage, and flooding. The following are a few methods to consider:

  • Build a Gravel Base Layer
  • Form a Crown to Your Gravel Roadway or Driveway
  • Create Proper Drainage
  • Use a Gravel Grid
  • Control Gravel With a Border

Build a Gravel Base Layer

When constructing a gravel driveway or roadways on an uphill, it’s vital to build it to an 8–10 inches depth. This can be performed by using heavy machinery to excavate and grade the proposed roadway or driveway, or by placing gravel over an existing material with the intention to install a border after the gravel is in place. 

Ensure you do the following when constructing a gravel driveway or roadway on a slope so it can withstand vehicle and foot traffic without slipping:

  • Excavate up to 8-12 inches and grade the driveway. Another option is to grade the site and plan to confine gravel once it is laid. This makes the gravel driveway on a slope to be more stable.
  • At this point, plan and build any culverts you want to run beneath the gravel.
  • Distribute 4 inches of #3 crushed rock or stone, then roll it out to compact 
  • Scatter 4 inches of crushed stone #57 on the ground, then roll it out again to attain compaction.
  • Finally, distribute 4 inches of crushed stone #411 on the ground, then roll to compact it.

It is worthy of note that your gravel should be laid in layers, with the use of a lawn roller in order to compact each layer. Migrating from large to smaller gravel is essential for constructing a long-lasting gravel base, which enables adequate drainage and compaction, increasing durability and making the area more resistant to flooding.

Form a Crown to Your Gravel Roadway or Driveway

When gravel is being installed, make sure it is not laid in a flat or level layer from one side to the next. Because doing this results in a water pool and increases the likelihood of gravel rolling downhill. Instead, construct your driveway or roadway with a larger elevation in the middle that gently falls to the sides. This ridge, or “crown,” will direct rainwater away from your gravel, keeping it dry and secure.

In addition, make sure you do the following if using this method:

  • Create a crown along the middle of the driveway or roadway when layering and compressing the gravel.
  • On either side of the crown, gradually slide the gravel downward.
  • The crown should stand 3–6 inches above the margins.
  • This crown will aid your gravel in shedding water and resisting erosion caused by water. Besides, it helps stabilize your gravel driveway on a slope even more.

It would be a tremendous plus if you can help your gravel shed water in any way. Vehicle activity on a waterlogged or soggy section of gravel is one of the most common causes for gravel to slide downhill.

A simple gravel driveway with plants and trees

Create Proper Drainage

Gravel slides downhill or forms deep ruts as a result of flooding and washouts. A dry gravel driveway or roadway has a much better chance of staying put. So, if you’re constructing a new gravel driveway, it is ideal to install concrete culverts under the gravel to send water beneath the gravel away, rather than over the top. In addition, you can dig a trench drain across existing gravel driveways or roadways to keep them dry.

Make sure you do the following if you are adopting this method:

  • Ascertain where water from the hill runs onto the gravel driveway.
  • To catch the water before it hits the gravel, ensure you dig a drainage trench; downhill is the way to go.
  • If you’re laying a new gravel roadway or driveway, make sure to place culvert pipes below the gravel in flood-prone locations.
  • Channel your drainage trenches to route water via culverts if you have them beneath your gravel already.

The excellent thing is that since your gravel is set on a slope, you have the perfect setting for digging drainage trenches that safely move water down before it puddles on your gravel. This makes it easier to avoid flooding and washout than it would be in flat places.

Use a Gravel Grid

Another great method to keep a gravel driveway on a slope is to install a geotextile or plastic grid prior to pouring gravel. The grid’s honeycomb construction creates many “cups” that catch and hold the gravel in place. In addition, anchor the grid to the soil with rebar stakes or any similar implement prior to placing gravel if you want to achieve extra stability.

Take note of the following:

  • To hold gravel in place, use a plastic grid
  • It’s critical to anchor a gravel grid to the ground before spreading gravel; else, both the grid and the gravel may slide.
  • Fill your grid with crushed stone #3 (which is a 1/2–2 inch gravel mix) after it has been installed.

Fill the gravel grid with #3 crushed stone and then top it over with smaller gravel like #57 and #411 to create a finer, more compact gravel driveway or roadway. Even on a steep uphill, this system will remain in place.

Control Gravel With a Border

Gravel can be contained and kept from sliding by using a border of stones, bricks, or pavers. In addition, this small wall will restrict the gravel from moving outward if you’ve constructed a deep gravel base. Don’t be concerned about the boundary acting as a water trap because flooding will not be an issue if you’ve constructed gravel from a variety of sizes and installed drainage with it.

To achieve the best result with this method, do ensure the following are in place:

  • To keep your gravel driveway on a slope contained, ensure you line it with stones, concrete, or even wood.
  • Your gravel can be prevented from spreading by a border, which can also keep it stable and compacted sufficiently to avoid slipping downhill.
  • A border will not raise the risk of flooding if the gravel is correctly constructed with a good drainage system.

Borders can be appealing features for your property in addition to keeping your gravel in place. A well-marked and bordered driveway looks far nicer than a jagged gravel driveway that ends on both sides.

How Is Gravel Applied?

Anytime you want to carry out the application of gravel on your driveway or roadway, ensure you use the three sizes of gravel available. There are three strata; the first of which consists of baseball-sized rocks, or #3 stones as they are known in the industry.

The first layer establishes a solid base for your driveway while also ensuring proper drainage. Typically, the first layer is 4 inches thick.

Another layer of 3-4 inches golf-ball-sized boulders makes up the second layer. These are the common #57 rocks which are the best gravel for a sloped driveway. The transition between the first layer and the top layer is formed by these rocks.

The uppermost layer is made up of marble-sized rocks of various colors. It all boils down to the stone you select. Also, note that each layer will require machine-crushed stone.

Conclusion

Lots of property owners hold the assertion that it is almost impracticable to keep a gravel driveway on a slope due to the migration characteristics of gravel. While this belief may not be far from the truth, it is still possible to build a stabilized driveway on a slope using gravel. 

If the proper method is adopted, your sloped driveway can be constructed with gravel and it can still be as stabilized and durable as it is with the leveled ground. In all, ensure you contact a professional paving contractor if you are planning to embark on such a project for your residential property or business area.

Salt For Asphalt Driveways – Will it Degrade Your Property?

Salt For Asphalt Driveways

As the time approaches the cold and long months of the winter season, you will want to be proactive in all aspects. Including ensuring that your driveway is secured from the icy and snowy conditions accompanying the winter season, making it difficult and unsafe to use your asphalt driveway.

Many homeowners and business owners usually use salt for asphalt driveways as a standard solution to post snowfall and blizzard effects. 

Is salt damaging to asphalt driveways?

Salt is widely used in the winter season to manage asphalt pavement; however, many people are worried about its effect on their driveways. The good news is that:

It is a popular misconception that using salt for asphalt driveways degrades the driveway. Hot-mix asphalt is made to withstand the freezing and icy conditions of the winter season. Hence, salt would not affect the surface of your asphalt as long as it is installed properly. 

However, a salt application can affect other unsealed materials like brick pavement and concrete because the bonds that bind these materials together can be broken down by salt, and they also freeze quicker.

If you are worried that salt will create potholes on your roadway, know that potholes on a driveway are not the direct consequence of salt application. When you observe crackling on your asphalt surface, you should seal it immediately before it is too late. 

Potholes are commonly developed by water that gets under the ground surface. During the expansion and contraction of the water, the gravel foundation becomes weakened, and the weight of vehicles is what typically contributes to the development of potholes.

But does driveway salt actually melt ice?

Many people believe that driveway salt melts ice is a misconception because it is not really the case. Putting salt on your driveway does not melt it; instead, it modifies the water chemistry. 

Water at 32° F freezes. When you put salt into the water, it decreases the water freezing point, indicating that the water can freeze only at the point it gets to an even lower temperature. Therefore, you should expect to have enough ice left on your driveway if the salt you put on it (irrespective of the quantity) does not lower the freezing point enough.

Pros and cons of using salt for asphalt driveways

People living in environments threatened by snow and ice during the winter frequently turn to salt applications to make it safer. 

The many benefits of using salt in the winter are possibly why it has been used ever since and continues to be the most famous deicing material on the market today. It is readily available, inexpensive, and proven to be useful for melting ice and snow. 

Although there are benefits of using salt on asphalt and concrete, there are also many disadvantages. Rock salt is a widely used material for this job, but there is a major worry that using salt on asphalt creates hideous and potentially harmful effects. 

Therefore, it is worthwhile to make yourself conscious of some of the many adverse effects that come with the use of salt for deicing before applying it to your asphalt driveway.

The pros:

The advantages of using salt for asphalt driveways include the following:

  • One of the biggest advantages of applying salt on your asphalt driveways and other paving properties is that it prevents snow and ice buildup. Deicing is critical when you have asphalt pavement in your home. 
  • In certain situations, preventing the ice from forming on your driveway and roadway will significantly minimize the damage incurred by slipping, falling, or sliding on the ice. 
  • It is very pertinent to apply salt on your asphalt driveways or parking lots before and after winter to prevent snow and rain from forming a thick layer of ice on them. It also makes it easier to remove the precipitation that falls on your treated surfaces.
  • Applying salt to driveways increases asphalt surface friction, making it an extremely efficient way to minimize dangerous and even fatal vehicle accidents on slippery roads in poor conditions. 
  • Road salt is a practical lifesaver and happens to be pretty inexpensive. Many states use it because it is readily affordable.
  • Salt does not degrade asphalt if it is correctly installed for your parking lot or driveways by a professional. Hot-mix asphalt pavement is a mixture of sand, stones, and petroleum combined in quantities to meet the needs of the area being paved. Your asphalt pavement is designed to endure the freeze-thaw cycle and is not influenced by salt or other deicing agents.

The Cons:

The following are cons involved with the use of salt for asphalt driveways:

  • Road salt aggravates the damage to already degraded asphalt as a result of the combination of high precipitation levels, cold winter temperatures, and traffic weight. This is because water saturated with road salt boosts the number of cumulative freeze-thaw cycles. Therefore, road salt can result in potholes under severe cold and on already damaged roads.
  • Road salt commonly causes corrosion of vehicle parts. Many vehicle owners park their car in a garage, allowing the snow, ice, and salt to sit and rot away at the car’s building components. This small mistake speeds up rusting and triggers the exhaust and muffler system, piping, coil springs, and frame to suffer harmful effects. 
  • Due to the chemical composition of road salt, the more your vehicle interacts with it, the rustier it is probably to get. This is because precipitating water places parts of metal cars in close contact with each other. As the free-flowing ions in road salt interact with water, iron oxide formation can be increased by increasing the rate at which it forms. This implies that your car can easily become rusty unless you regularly wax and wash it during and before winter.
  • Salt can be hazardous to the environment. While salt helps to prevent accidents related to winter, it does affect the environment. The salt can impact plants, animals, and local wetlands in water runoff. Salt mainly causes dehydration, which results in foliage damage and triggers osmotic pressure that hurts the development of roots.

Rock salt/other deicer alternatives

Due to the many apparent effects of using rock salt for asphalt driveways and other home pavements, many homeowners and even the government are seeking safer alternatives to rock salt as a means of taming winter roads. There are many rock salts substitutes; each has its uses and may not be suitable for every condition. 

Below are a list of six rock salt alternatives you may use for your asphalt driveways and other home foot-traffic pavements. These alternatives are not all inherently exclusive, so be free to mix and match and find the option that works perfectly for you.

  • Calcium chloride (Cacl)
  • Magnesium chloride

Calcium chloride (Cacl)

Calcium chloride is a by-product of certain chemical production processes, which is an excellent choice in the country’s sub-freezing areas that are hitting temperatures as low as 24°F. Its properties, especially regarding removing solid ice, enable it to be much more efficient than rock salt. It acts rapidly and works almost instantly, but its snow-melting and deicing capabilities continue to work for up to 24 hours after you apply it on the pavement.

It is necessary to properly store Calcium chloride in plastic or metal bins with lids since it easily sucks up water. Crew handling this product should wear good protective kits like respirators and gloves to prevent its effects on the body.

If you use Calcium chloride properly, it won’t damage plants, but it can leave an oily, slippery trace. And because of this, it may not be the option of preference in and around buildings with high foot traffic rates. 

Magnesium chloride

This is another deicer among rock salt substitutes that comes in a liquid solution or granule form. It is environmentally friendly to use around plants, but professionals should not apply it too hugely due to its slippery nature. The granular form sucks up water too easily, so crews should ensure to store it in a dry place and cover it, or it will harden. 

Magnesium chloride resembles calcium chloride, but it is potent only down to 1º F (-17.22° C). In comparison, it does not melt ice as quickly as calcium chloride, but it is much more potent than rock salt.

Potassium chloride

Potassium chloride is an all-around right deicer product available in pellet form and shares some fertilizers’ chemical composition. It is suitable for pedestrian areas and performs very well when dealing with temperatures between 10 and 12°F. 

Although not exactly perfect, the substance is much less detrimental to the environment around it. Sadly, the price tends to be almost twice that of rock salt, and you need almost double the quantity to cover the same area.

That makes it only appropriate for small properties or coverage areas, particularly for anyone on a spending plan.

Potassium acetate

Potassium acetate is an environmentally friendly liquid solution that can be used as an alternative to rock salt to keep snow and ice from developing and sticking to paved surfaces. It is eco-friendly and exists in liquid form. It is recommended that technicians should apply it before a winter storm to achieve optimum efficacy.

Potassium acetate is more efficient and capable of melting snow and ice even at temperatures below 76°F, and as a result, it is the most costly option on the list. It is not a good choice for larger projects, particularly in regards to eliminating snow and ice from long stretches of road.

Cat litter

This rock salt alternative is phenomenally effective when it comes to melting snow and deicing different areas. It is more costly than rock salt, hindering its feasibility for large-scale projects. Still, it is an excellent substitute of rock salt for asphalt driveways and other outdoor pavement that homeowners and property managers can adopt to keep their local areas safe. 

The biggest problem with cat litter is that once the snow melts, particularly after the winter seasons are over, it can create a mess.

Snowmelt mats

Snow melting mats are built to be installed on a highly traveled area to help clear away snow, ice, and sleet. They usually have integrated wiring and heating coils to heat the mat and melt away the nearby snow. They are small in size and usually consume energy; hence, they need an active power source, resulting in larger energy bills over the winter.

How to properly use driveway salt

It is not good enough to choose the right salt to use, but it is also pertinent to use the right salt properly to effectively melt the ice and snow without impacting your pavement adversely. Below are a few things to note when using salt for asphalt driveways and other outdoor pavements:

  • Spread it evenly to cover as much surface area as possible without using too much.
  • Do not apply too much salt to your driveway, as it can cause severe damage to your driveway and lawn soon after the snow melts.
  • Clean paws and hands, as many salts are abrasive and can make your skin itchy and red
  • Choose the right salt that suits the temperature of the region it is being used. 
  • Although it may seem like hard work to you, always ensure to shovel the snow before you apply salt to the driveway.

Conclusion:

Whether you are dealing with rock salt or one of its several substitutes, it is necessary to consult a snow and ice specialist. They can get you a cost and product breakdown, product durability, facility requirements, the number of hours required, the amount required for desired results, as well as possible environmental hazards. 

In most situations, these products can have a detrimental effect on the pavement surface if you use too much or too little of it, making it dangerous, if not more so.

Furthermore, it is vital to take into account the material you use and the best way to apply it to nearby areas. 

Using one of the several alternatives to rock salt for asphalt driveways discussed here eventually means fewer volumes of rock salt being added into the atmosphere and local infrastructure, and that’s better for all of us.

How Steep Can a Paved Driveway Be

Exploring the world of driveway slopes is crucial for both safety and functionality. In this insightful guide, we delve into the key question: How steep can a paved driveway be? Understanding the limitations and optimal design strategies is essential for homeowners and contractors alike.

The maximum recommended slope for a paved driveway is typically around 15%. Beyond this, safety and accessibility issues arise, particularly in adverse weather conditions. Steeper slopes, up to 20%, might be manageable with special considerations like textured surfaces or additional drainage solutions. However, local regulations and the specific vehicle types used should always be considered, as they can influence the practicality and legality of steeper driveway designs.

When designing a driveway, it’s crucial to balance the slope with the property’s topography and usage needs. Key considerations include the driveway material, local climate, and intended vehicle traffic. Expert advice is invaluable in achieving a driveway that is both functional and compliant with local building codes. Dive deeper into our comprehensive guide for more insights on achieving the perfect balance in driveway slope and design.

How Steep Can a Paved Driveway Be?

As homeowners embark on the journey of paving their driveways, the question of incline becomes a pivotal consideration. In this exploration, we delve into the nuances of driveway slopes, from navigating building code requirements to addressing the challenges posed by steep slopes and discovering custom solutions for unique approaches.

Paving Limits and Slopes

It’s commonplace for most experienced and reputable paving contractors to easily pave driveways’ with a 12%-15% slope. In extreme circumstances, with the proper architect\design firm, you may be able to find a very skilled company to pave up to a 25% angle which translates to 25 feet of rise over 100 feet of driveway. Anything over 25% will have to be surfaced with some other material than asphalt.

Navigating Building Code Requirements

According to the American Concrete Pavement Association, if your driveway’s angle is over 15%, it’s important that you are talking with a reputable company; one that knows the    ”in’s and out’s” of your local building code requirements and who is knowledgeable in how to design and engineer a driveway that will survive the tests of time and nature.

Those driveway’s with 15% angle or more, require more complex designs, and in some cases, asphalt cannot be applied if the grade is too steep, due to the compactors not being able to safely and effectively operate. So make sure when you are searching for the right contractor, you verify some of their work; ensuring they have done similar jobs and the work has held up.

Challenges of Steep Slopes

Having a driveway that has a steep incline offers several challenges and weather is definitely a common factor.

Rainwater, snow, and ice all need to be able to drain properly off of your driveway. If the drainage system is built incorrectly at the base of your steep driveway, any paving job you have done or driveway installation you get will be ruined, unless designed properly. It is just as important once you have decided how steep your driveway can be paved, to ensure that you keep up on the maintenance.

  • Keeping snow, ice, and accumulating puddles of water off the surface will lengthen the life of your driveway. If you are not able to keep the snow and ice off yourself, hire a company to maintain your driveway.
  • Talk with your paving contractor and know what you need to do for upkeep; re-sealing, filling cracks, grading and other preventative steps may be needed to prevent further cracking and damage.
  • If a problem arises with your driveway, such as a pot-hole or cracking- do not wait for a long time before calling out someone to repair the problem. The longer you wait, the worse the issue becomes.
