Rehabilitation of Overstressed Rigid Pavements

The maintenance/repair needed during the life can be covered under Concrete Pavement Restoration (CPR) procedures like sub-seal, full-depth patching, partial-depth patching, load transfer restoration, diamond grinding and joint resealing. We can see that these procedures if undertaken can overcome the defects that may crop up during the designed life/utilization of the pavements. Problem

Diamond Grinding – Pavement Interactive

Diamond grinding (Figure 1) refers to a process where gang-mounted diamond saw blades (Figures 2 and 3) are used to shave off a thin, 1.5 – 19 mm (0.06 – 0.75 inch) top layer of an existing PCC surface in order to restore smoothness and friction characteristics. Most often, it is used to restore roadway friction or remove roughness caused by faulting, studded tire wear, and slab warping
