In CPCD, any cracking, breaking, or spalling of slab edges, on either side of a transverse joint, need to be repaired. The repair can be full-depth repair (FDR) or half-depth repair (HDR), depending on the extent of the breaking or spalling. If the distress extends through the depth of the slab or hinders the ability of dowel bars to transfer load, FDR is required.

In CRCP, failures in transverse construction joints require joint repairs. Additional longitudinal steel is used at the transverse construction joints to accommodate large concrete stresses, which requires special attention for concrete consolidation under the longitudinal steel. If proper consolidation is not provided at the transverse joints, delamination and distress can result as shown in Figure 10-27. Any repair of the transverse construction joints requires FDR.

As for the boundaries of joint repairs in CPCD, if the patch boundary falls within 6 ft. of an existing undoweled transverse joint that does not require repair, extend the patch to the transverse joint. If the boundary falls on an existing doweled transverse joint, and the other side of the joint does not require repair, extend the patch beyond the transverse joint by about 1 ft. to remove the existing dowels.
