Concrete pavement is a rigid pavement structure, which distributes heavy axle loads over a large area by beam action. This means concrete pavements are less sensitive to the sub-grade support and do not require the thick road base/ sub-base layers like asphalt concrete pavements.
JRCP uses contraction joints and reinforcing steel to control cracking.Transverse joint spacing is longer than that for Jointed Plain Concrete Pavement (JPCP) and typically ranges from about 7.6m (25ft.) to 15.2m (50ft.). Temperature and moisture stresses are expected to cause cracking between joints, hence reinforcing steel or a steel mesh is used to hold these cracks tightly together. Dowel bars are typically used at transverse joints to assist in load transfer while the reinforcing steel/ wire mesh assists in load transfer across cracks.
