Many homeowners choose asphalt as the most reliable construction choice for a durable driveway. However, you may sometimes need to fix cracks in your asphalt driveway to keep it in optimal condition.
Asphalt pavement may last for about 20 years if properly installed and maintained. A driveway should be resealed around every three years; more frequently, asphalt driveway cracks form and require repair. Asphalt driveway cracks are often caused by the aging process, a subbase shifting due to freezing and thawing. If left unattended, cracks will allow moisture to enter and eventually cause the sub-base beneath the asphalt to erode.
If you want to prevent the cracks in your pavement from worsening, you need to be proactive and fix them before they get bigger. That’s why we created this comprehensive guide on how to fix cracks in your asphalt driveway and the best fillers for your next asphalt driveway crack repair.
Why is my asphalt driveway cracking?
Any asphalt can develop cracks due to variations in moisture retention and temperature. Let’s detail how every season of the year might impact your driveway. We will also look at other factors that affect the overall health of your driveway.
The Freezing and Thawing Cycles in The Winters
After significant snowfall or rain, moisture will penetrate the surface and soak into the ground below. The moisture then expands due to temperature changes, causing the asphalt to crack. The winter’s sequence of freezing and thawing produces the majority of cracks you might find on your driveway.
The Expansion of Asphalt in The Summer
Asphalt may expand under the strain of intense heat, leading to fissures. The heat can also cause cracks in your driveway during the hottest parts of the summer when the hours seem to disappear for “years,” and the temperatures soar to dangerous heights. These fissures might grow into more serious issues if not addressed.
The Age of Your Asphalt Driveway
Your asphalt susceptibility to deterioration depends heavily on its age. Asphalt driveways’ propensity to break increases with age. As time goes on, the substance starts to deteriorate and loses its inherent capacity to endure the pressures that your surface is subjected to daily.
Older roads are, therefore, more likely to sustain damage when heavy rain or a freeze-thaw cycle occurs.

Movements of The Earth’s Plate
The ground moving beneath your asphalt is a principal reason for cracking asphalt. The earth’s plate is always moving. The majority of asphalt driveways are built on top of the gravel. During the lifetime of your driveway, the gravel underneath will be affected by the ground’s movement and cause cracks to emerge.
The movement might be due to the earth’s natural sequence or strong storms. Whatever the case, it is always safer to fix them immediately to protect your tires from damage.
Should cracks in the asphalt driveway be repaired?
Cracks on asphalts should always be repaired. Here’s why: If your asphalt develops a crack, it will probably continue to expand if you don’t fill it in. The stresses that caused the first crack to propagate still exert pressure on the pavement, which causes the cracks to enlarge.
Moisture entering the cracked asphalt expands when it freezes or dries off, causing the pavement to become more spaced. These spaces weaken the integral material of your asphalt and, with time, become a permanent weak spot on your driveway. These weak spots might always pose a problem even after the cracks have been sealed. To protect your driveway and enjoy a long-lasting tarred road, it is best if you remedy cracks the moment they are observed.
Applying a fresh sealant layer on cracked asphalt is the best way to prevent weakness on your driveway. Read our simple step-by-step guide to find out how cracks on asphalt are repaired.
