Types of rigid Continuous Reinforced Concrete Pavement (CRCP)

 Continuously reinforced concrete pavement does not require any contraction joints.
 Transverse cracks are allowed to form but are held tightly together with continuous
reinforcing steel.
 Research has shown that the maximum allowable design crack width is about 0.5 mm
(0.02 inches) to protect against spalling and water penetration (CRSI, 1996[1]).
 Cracks typically form at intervals of 1.1 – 2.4 m (3.5 – 8 ft.).

 Reinforcing steel usually constitutes about 0.6 – 0.7 percent of the cross-sectional
pavement area and is located near mid-depth in the slab.
