The best way to protect the investment in your asphalt pavement is to be diligent about “preventative” maintenance such as crack filling and seal coating. But once asphalt decay has advanced past the stage where these are an appropriate remedy, it is necessary for a “reactionary” remedy. Asphalt patching is necessary for areas that are heavily cracked (or “alligatored”), sunken, exposed (potholes), or raised by roots or water damage.
The perimeter of the affected area will be saw-cut to provide a clean, professional-looking edge, and to provide maximum structural integrity. All cut should be made at least 12-18″ outside of the visible surface damage because most damage starts underneath, working itself upward and showing itself at the surface last. If the area is too small, there can soon be new damage around the perimeter of a new patch.
The old, decayed asphalt will be removed and disposed of (asphalt is the most recycled material in the world, measured by weight!). The sub-base will be inspected and appropriate action will be taken (such as clipping tree roots, bringing new crushed rock, or providing new compaction). New hot mix will then be placed and compacted. Tar seal is applied to the seams (of old adjacent to new) to prevent moisture penetration. As a general standard, asphalt thickness should never be less than 2 inches. Areas that have high traffic volume or heavy loads may require a much greater thickness.
