No Concrete Road can not be designed without reinforcement.

Reinforcemnet is provided in two directions, longitudinal and tranverse directions to control cracks.

The longitudinal reinforcing steel keeps the naturally occurring transverse cracks in continuously reinforced concrete pavement (CRCP) tight, thereby providing high level of load transfer across cracks. When transverse cracks are kept tight, aggregate interlock also transmits the shear forces across the crack, resulting in reduced wheel load stress and fatigue damage in concrete.

Transverse reinforcing steel is used to provide support for longitudinal steel. It also keeps longitudinal cracks tight if they occur
