How to Install New Asphalt
A new asphalt installation is a brand new start for your pavement. It will typically follow this process:
Step 1: Demolition and Removal
It begins with removing whatever the existing surface is and disposing of it. If the existing surface is asphalt, it can be recycled and used in future asphalt surfaces, which will save you money on material.
Step 2: Grading and Sloping
Before laying anything down the surface must be graded, this will allow water to drain away from the pavement and into a grassy area. Your contractors may also need to re-shape the area to give it a sloping surface which will help direct the water away.
Step 3: Prepping the Sub Base
The sub base is the bottom most layer, it will be supporting your new pavement.
Step 4: Adding the Binder Layer
The binder layer is a large aggregate mixed with oil, which makes it strong and durable. Once this step is done it’s time for a proof roll.
A proof roll is a test to be sure the underlying surface is strong enough to support the new asphalt. If the proof roll finds soft areas, undercutting can be used to repair them. The process involves digging below to surface about 2 or 3 feet and replacing the soft soil with stronger aggregate material.
Step 5: Installing the New Asphalt Surface
The new is asphalt laid.
Step 6: The Final Roll
Once the asphalt has been laid, the surface will be smoothed and compacted.
