· 10. Scaling of Concrete -Defects of Road for Rigid Pavement. The wear-tear of the rigid pavement surface due to heavy traffic is scaling. Another reason for the accelerated scaling of the concrete surface is over-vibration during construction. Due to over-vibration, the cement slurry comes to the surface and sets.

The pavement structure is best characterized by slab depth (D). The number of ESALs a rigid pavement can carry over its lifetime is very sensitive to slab depth. As a general rule, beyond about 200 mm (8 inches) the load carrying capacity of a rigid pavement doubles for each additional 25 mm (1 inch) of slab thickness. Drainage coefficient.
