Typical distresses in rigid pavements

The surface distresses in rigid pavements may be classified into cracking, deformation (distortion), disintegration and loss of skid resistance. 

Before describing in detail the distresses and their causes, it should be mentioned that effective maintenance/treatment of the distresses in rigid pavements with cement mortar or concrete (unreinforced or reinforced) is too difficult and sometimes impossible. For this reason, bitumen and asphalt are the materials greatly used in maintenance of rigid pavements.
