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) operations. 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, as discussed in Chapter 16. In some cases, such as dowel bar retrofit and diamond grinding, the CPR strategies fix load transfer or smoothness deficiencies in the original pavement and make it better than new. A detailed discussion of CPR operations, with photographs, is provided
in the AASHTO/FHWA/Industry Joint Training Participant’s Manual, Construction of Portland Cement Concrete Pavements (ACPA 1996a). A CD with PowerPoint presentations that accompanies this manual may be purchased separately from ACPA. Sections in the manual include:
• general overview of CPR (pages VIII-1-VIII-13); • slab stabilization operations (pages VIII-14-VIII-25); • full-depth patching operations (pages VIII-26-VIII-44); • partial-depth patching operations (pages VIII-45-VIII-58); • dowel bar retrofit (pages VIII-59-VIII-68); • diamond grinding operations (pages VIII-69-VIII-82); • joint and crack resealing operations (pages VIII-83-VIII-93). Joint and
crack resealing is discussed in Chapter 15.
