Cup Cracking / Cupping Depression

Cupping (also called cup cracking or cupping depressions) is caused by the deterioration of the substrate or base material. The surface pavement loses base support and collapses, forming a channel-like crack or cup-like depression.

Pavement cracking will allow water channeling and infiltration, which will further erode the base material, creating fatigue cracking, as well as larger voids and potholes
