There are two main types of asphalt repairs procedures that will provide a suitable fix to most asphalt related issues, asphalt removal and replacement and asphalt surface patching. Asphalt removal and replacement involves the removal of the entire layer of pavement surface down to or including the stone base, depending on the condition of the stone base. The stone is then re-compacted, a tack coat is applied to the vertical surfaces or any existing asphalt that remains, and the new asphalt pavement is placed in the repair area. Surface patching is a more temporary fix and should only be considered for a surface that is in relatively good condition. This process does not involve the excavation of the existing surface or subbase. The asphalt is simply layered over the existing surface and feathered to match the in-place grade. In some cases, a rebate is milled into the surface, which eliminates the need to feather-edge the patch.
