There are so many options to repair or replace your damaged asphalt paving. One of the most secure repairs is an asphalt overlay. Asphalt overlay is a paving method of applying a new layer of asphalt on top of a deteriorating surface. Rather than tearing up an old asphalt surface entirely, an asphalt overlay project will use the existing layers as the base for the new asphalt surface. Some asphalt surfaces that have, over the years, experienced severe damage like rutting, potholes, large cracks, and expansions will need to be milled before an overlay is applied. If the damage to your asphalt pavement has gone too deep into the subsurface and base of the asphalt, this method would not be suitable to repair your driveway. There is always the chance that the damage is too severe and a new driveway would be a better, long lasting option.

Our Asphalt Assessment:
Firstly, @Bradley Asphalt, we would book a free appointment to examine the damage to your driveway and assess if overlaying your driveway would be your best solution. Not all existing asphalt surfaces are suitable for overlays. If your paving has structural damage such as potholes, root damage or rutting, we will have to replace the driveway and build a solid foundation. Asphalt surfaces that are not draining water correctly may also not be suitable for asphalt overlay because the surface may need to be regraded to handle water more effectively.
If we decide that this method of overlaying is suitable for you we will go ahead with the Asphalt milling, removing the top layer of your asphalt surface that has taken on cracks, raveling, or other damage. The old layer that has sustained damage must be removed to ensure an even, solid and smooth bond when the new asphalt is applied, and to maintain a level surface. An asphalt milling machine will grind down 1″ to 3″ depending on the wear of the asphalt surface. The ground surface material will be hauled to an asphalt recycling plant where it can be integrated into new asphalt mix designs.
The most important part of an asphalt driveway is it’s base. If this is correctly done from the beginning, you will have many years of trouble free use. The base of an asphalt surface may need to be replaced in areas where potholes, rutting, and sinking have formed. To prevent similar issues appearing in the future, the base of the asphalt surface will be rebuilt using multiple lifts of aggregate and asphalt.
Once the existing asphalt surface has been prepared,and we are satisfied that it is a good, solid, level base, the asphalt overlay can be paved on top of the surface. The amount of asphalt overlay applied to the surface will vary depending on the thickness of the existing surface, but typically will be within 1.5″ to 2″ thick.
Overlay driveways are very good options for maintaining your asphalt paving surface and are generally cheaper than a brand new asphalt installation.
