Due to its versatility, durability, and flexibility, asphalt hot-mix is one of the most popular materials for driveways and roads the world over. Once laid, it provides a smooth, flexible and durable finish, which is generally ready to drive on within an hour or two. It is ideal for driveways, car parks and other areas that experience a high traffic volume and/or drag caused by turning wheels.
Asphalt hot-mix is a combination of approximately 95% stone, sand, or gravel bound together with bitumen, which is itself a product of crude oil.
The resulting Hot Mix Asphalt is loaded into a truck and transported to the job site, laid onto a prepared and stable base at a temperature between 150 – 190 degrees, then compacted using a heavy roller. There is minimal downtime, cars and traffic can use the pavement as soon as it has cooled, generally within an hour or two.
Asphalt is sometimes referred to as a flexible pavement as it can largely resist the stress imposed by slight settlements of the subgrade without cracking.
Asphalt can be 100% recycled and is currently the most recycled construction material in the world.
Generally, the terms asphalt and bitumen are interchangeable and typically refer to the surface sealant or finished product.
Asphalt is fast to construct, easy to maintain, and cost efficient. Properly designed and maintained surfaces can be expected to last 15-25 years. Known as a ‘green pavement’, asphalt is 100% recyclable and uses little energy in its production and construction, making it an excellent choice for the environment and road users alike.
