Jointed Reinforced Concrete Pavement (JRCP)
Jointed reinforced concrete pavements (JRCP) contain steel mesh reinforcement (sometimes called distributed steel). In JRCP, designers intentionally increase the joint spacing and include reinforcing steel to hold together mid-panel cracks. The spacing between transverse joints is typically 30 ft (9 m) or more with some agencies using a spacing as great as 100 ft (30.5 m). During construction of the interstate system, most agencies in the Eastern and Midwestern U.S. built JRCP. Today only a handful of agencies employ this design due to performance issues caused by the embedded steel being incapable of holding together mid-panel cracking and the resultant erosion/faulting of such cracks.
