Have a look at the step-by-step process on how to install an asphalt pavement that can be used as a driveway.
- Step 1: Removal following the Demolition
The first and the foremost step you should follow in the Asphalt installation process is to remove the existing surface whether it is concrete, asphalt or pavers. Demolition and removal are done with the help of heavy machinery like forklifts and bobcats when necessary. Front-loaders and large dump trucks are also used if needed. The debris is then removed. If there is old asphalt or remnants, most contractors recycle them and use the new and strong asphalt which doesn’t become a burden on the environment.
- Step 2: Sloping and Grading
By making use of clean slate technology, most contractors prepare the surface for appropriate water drainage. Automatic motor graders and laser-guided transits would be used to grade the surface to be paved to make sure that the water would run off appropriately. Proper water drainage is very important to your Asphalt as water could cause major damage which includes cracks, heaving and potholes.
- Step 3: Prepare the Sub Base
The most important part of any new Asphalt surface could be the sub base. It would provide a stable surface to support the new pavement. The sub-base is a frost barrier that would help reduce winter damage due to thawing and freezing. During installation, base thickness, stability and compaction remain the essential steps. If the sub-base is not appropriately compacted, the asphalt surface on top will not provide longer durability.
- Step 4: Proof, Undercutting, Roll and Sub Base Repair
Once the sub base gets fully graded and compacted, an extra step known as proof and roll is taken to make sure that the underlying surface remains strong and ready to support new asphalt.
- Step 5: Surface Course and Binder
Once the sub base gets laid and any soft areas are identified and repaired, it is time to add the binder. The binder layer is a large aggregate that gets mixed with oil which would make it strong and durable. The binder layer could be thought of as the strength of any new asphalt surface.
- Step 6: Install new Asphalt surface
Once the supportive structures of a new Asphalt surface get installed, the top layer of fresh asphalt is added to provide a smooth and clean ride. Surface Asphalt is made of small aggregate, oil and sand. The combination of materials would create Jet-black Asphalt. When it is installed appropriately, it would provide a shiny and smooth ride with an attractive finished surface.
- Step 7: Transitions and Joints
It is a rare thing to install an Asphalt surface that doesn’t connect to existing driveways, roadways or parking lots. Asphalt paving contractors should find a way to smoothen the transition from the old to the new surface. The transitional areas would require special attention to make sure that the grading and water run-off remain appropriate.
