Do you see cracks in the asphalt that resemble the rough skin of an alligator? Unless the cracks are repaired, the entire lot will have to be completely removed.
Solution: Grind, or slot cut the perimeter of the alligatored areas. Compact sub-base to 90-95 percent compaction. Tack vertical edges and install hot asphalt concrete in equal lifts and roll for proper compaction.
