HOT MIX ASPHALT SKIN/OVERLAY PATCHING - HOW WE DO IT

Code Black uses the following 6-step process to perform skin or overlay patching.
  1. Remove all debris.
  2. Clean the surface of the low problem area by sweeping, using a blower and/or power washing as needed. 
  3. Prime the surface to treat chemical spills, if present, to ensure the new hot mix adheres properly.
  4. Apply a tack coat (a liquid bonding agent). 
  5. Resurface the area with hot mix asphalt by hand or with machinery depending on the overall size of the area. 
  6. Complete the repair by edging it with hot rubber to seal the seam where the old and new asphalt meet to prevent water penetration and unraveling.
