Puget Sound Experts in Parking Lot Overlays & Patching | Action Asphalt
Action Asphalt Paving offers several commercial asphalt paving services to extend the life of parking lots. Most commonly, repairs include asphalt patching and asphalt overlays. If existing asphalt has degraded to the point of potholes or loose “alligatoring” (a cluster of cracked pavement), patching is recommended — a process in which old asphalt is removed and replaced with a new layer. In areas where the existing asphalt is still strong, a fresh asphalt overlay is suggested to reinforce the current surface. Applying an engineering fabric with the overlay further extends the asphalt life.
When the surface of an asphalt project deteriorates to the point of requiring repairs, an asphalt overlay can be a beneficial alternative to complete replacement.
New asphalt overlays are thin layers of new asphalt applied over the existing asphalt surface usually 1.5″-2″ in thickness.
New asphalt overlays don’t require the engineering and planning a complete installation necessitates, but careful consideration should be taken into account if the surface requires milling or grading needs to be preserved. Milling removes a basic level of existing material to an appropriate depth before a new layer of asphalt is applied, ensuring the new surface is consistent and smooth for pavement striping.
Asphalt patching is different from new asphalt installations and overlays in that the existing pavement is not altered before repairs are made. In the event there is no damage to the base of the pavement, patching can repair the surface of asphalt that is cracked, chipped, loose, or otherwise rough in appearance and texture in order to extend the life of the asphalt by 3-10 years.
New asphalt patches are used to improve the surface appearance of pavement or to stop water penetration. Patches are generally 1.5″ or less in relative thickness.
