Faulting of pavement
WebDescription. Cracking, breaking or chipping of joint/crack edges. Usually occurs within about 0.6 m (2 ft.) of joint/crack edge. Figure 1: Spalling along a linear (panel) crack. Figure 2: Onset of spalling up close. Figure 3: Bad construction joint spalling. Web(C) Raised joints. Generally caused by slab curling or faulting at the joints. Faulting refers to vertical displacement of concrete pavement slabs at joints. (D) Rutting. Caused in …
