ABSTRACT
Concrete pavement rehabilitation is necessary when maintenance is no longer sufficient to restore serviceability. One category of rehabilitation is termed concrete pavement restoration (CPR). This encompasses slab stabilization, full-and partial-depth patching, dowel bar retrofit, diamond grinding, and joint and crack resealing. Joint and crack resealing is also a maintenance technique. In some cases, such as dowel bar retrofit and diamond grinding, the CPR strategies fix load transfer or smoothness deficiencies in the pavement and may make it better than the original.
