CRACKING IN RIGID PAVEMENTS Rigid pavement consists of concrete slab. The concrete slab cannot be of indefinite length because concrete slabs of large lengths develop stresses in itself due to shrinkage and expansion and causes concrete slab to crack. These stresses may be due to temperature changes warping or friction. Cracks in a long slab may be random cracks and of irregular shape.
