What is tarmac?
Tarmac, derived from “tarmacadam,” is a road construction material renowned for its durability. It consists of crushed stones and gravel meticulously combined with tar, forming a resilient surface. This mixture, when properly laid, creates a weather-resistant and sturdy foundation suitable for various applications, such as driveways, roads, and pavements. The meticulous bonding process ensures longevity and structural integrity, making it a reliable choice in the realm of road-surfacing materials.
What is tarmac used for?
Tarmac is used for making car roads, airport runways, parking lots, driveways, motorways, caravan parks, and private roads. When a layer of crushed stone is mixed with tar and compacted with a migrating roller, it will form a smooth surface.
What is asphalt?
Asphalt is a paving material from a mixture of aggregates (sand, gravel, slags, waste or debris, or crushed rocks), binders, and fillers. Most builders use bitumen as a binder to put the aggregate together. Note that the asphalt mixture must be cohesive and resistant to withstand pressure and deformation. Asphalt mixtures are produced at different temperatures; Hot Mix Asphalt (HMA), Warm Mix Asphalt (WMA), and Cold Mix Asphalt (CMA).
What is asphalt used for?
Asphalt is used to construct and repair roads, railway tracks, airport runways, sidewalks, bicycle lanes, and driveways. The asphalt used to maintain our driveways and roads is produced in an asphalt plant.
Tarmac vs. Asphalt: Differences
Because tarmac and asphalt are widely used surface materials for driveways and have many similarities, it’s easy to mistake them for the same thing.
