Whitetopping - Wikipedia

Whitetopping is suitable for asphalt pavement with little deterioration, although repairs can be made to the asphalt if necessary. If the pavement is badly damaged, it should be completely removed and a new pavement should be installed. The pavement should be relatively hard, as well.

Thin Whitetopping - Pavement Interactive

Thin Whitetopping (TWT) is a 4 to 7 in. thick overlay bonded to an existing ACP to create a composite section. TWT is typically constructed at intersections where rutting and shoving in asphalt pavement continue to cause problems. TWT may also be used at access or exit ramps to interstate highways, entire sections of urban roadways, low-volume rural roads, bus lanes, and parking areas.
