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.
JPCP contains enough joints to control within the location of all the expected natural cracks. All necessary cracking occurs at joints and not elsewhere in the slabs. JPCP does not contain any steel reinforcement. However, it requires load transfer devices (e.g. dowel bars) at transverse joints and deformed steel bars (e.g. tilebars) at longitudinal joints. The spacing between transverse joints is typically between 5m (16.4ft.) and 6.3m (20.7ft.) for slabs of 200-300mm (8-12in.) in thickness.
