The desire to eliminate transverse movement joints from concrete pavements has led to the concept of an unjointed, continuously reinforced concrete pavement (CRCP). Tensile stresses within the slab are relieved by transverse cracks, which are kept tightly closed by the reinforcement to mintain load transfer across the cracks by aggrevate interlock. The spacing and the width of the cracks will have am important influence on the performance of a CRCP at four new road construction sites are compared.
