What’s the Process of Asphalt Paving?


A new asphalt installation is a fresh start for your roadway. Typically, it will proceed as follows:


Step 1: Dismantling and Removal of Existing Surface


It starts with removing and discarding of the current surface. If the existing surface is asphalt, it can be recycled and reused in future asphalt surfaces, saving you money on material costs.


Step 2: Sloping and Grading of Surface


Before laying down anything, the surface must be graded to allow water to flow away from the pavement and into a grassy area. Your workers may also need to reshape the area to provide a sloping surface to help guide the water away.


Step 3: Prepping the Sub-Base


The sub-base is the lowest layer and will support your new pavement.


Step 4: Addition of the Binder Layer


The binder layer is made out of a big aggregate mixed with oil, which makes it robust and long-lasting. When this stage is completed, it is ready for a proof roll.


A proof roll is a test that determines whether the underlying surface is robust enough to sustain the new asphalt. Undercutting can be used to correct soft areas discovered by the proof roll. The method entails digging 2 or 3 feet below the surface and replacing soft soil with stronger aggregate material.


Step 5: Laying a New Asphalt Surface

The fresh asphalt has been placed.


Step 6: The Last Roll

The surface will be leveled and compacted after the asphalt has been poured.
