Repaving involves full removal and installation of an asphalt pavement, which costs a lot of time, money, and effort. Therefore, it is wiser not to let your asphalt pavement fall into a state of disrepair. Take prompt action to stop any signs of deterioration from getting worse.

After years of use, the top layer of the asphalt can wear out and develop cracks, depressions, and potholes. At this point, minor repairs are not the answer, as they will only act as a temporary solution. You need to install an asphalt overlay.

An asphalt overlay is a paving method where a new layer of asphalt is installed on top of your present asphalt pavement’s deteriorating surface. However, to apply a pavement overlay, the pavement needs to be structurally intact, prepared, and capable of bonding. Depending on the type, elevation, and condition of the existing pavement, the asphalt surface is cleaned, leveled, repaired, and then coated with a binding agent.

An overlay is not suitable for all existing asphalt surfaces. If a surface has extensive structural damage like root damage, large potholes, ruts, or a drainage problem, then it needs to be ripped up completely, so the grading and drainage can be corrected and a new pavement installed.

Asphalt milling is done to remove the worn out top layer of the asphalt pavement, which has cracks, raveling, and other signs of damage. The old layer needs to be removed to maintain a level surface and even bond once the new asphalt is applied. An asphalt milling machine grinds down the asphalt surface by 1″ to 3″ or as needed.

In areas where there are ruts, potholes, or sinking, the base needs need to be replaced to ensure that the problem does not arise again. The base is rebuilt using asphalt and aggregate.

Once the existing surface is prepared, the asphalt overlay is paved on top. The quantity of the new asphalt applied to create the overlay depends on the existing surface’s thickness. However, typically, an asphalt overlay is 2″ thick.

To find out if an overlay can be applied on your asphalt pavement to extend its life and improve functionality, get a professional assessment from an expert paving firm. A good contractor can guide you on what the most effective solution would be depending on your pavement needs and pocket.
