- Skin Patching: This process is accomplished by cleaning the existing pavement, apply a tack coat (asphalt-based glue), and applying hot-mixed asphalt. The new asphalt is then mechanically compacted. Because the skin patches are placed on top of existing pavement, the finished surface may be slightly higher. The edges are blended in, or "feathered," as much as possible.
- Removal and Replacement: Also known as R&R, is used for more severe deterioration, especially when the underlying base has been affected. The damaged areas are squared off, saw cut, and excavated to a depth from two inches to two feet depending on the subsurface conditions. New aggregate is then added, if required, and compacted in preparation for the new asphalt surface. Finally, hot-mixed asphalt is placed over this layer and compacted. Any raveled surfaces (surfaces in which the aggregate is coming loose) are then smoothed out and re-striping can be done, if needed. Ace Asphalt also recommends treating the entire surface with a seal coat to restore the original look of the area and further protect it.
