When a pavement cools quickly, it tries to contract. . There are two types of thermal cracks — those occurring during a single falling temperature event, and.
As the temperature drops the restrained pavement tries to shrink. The tensile stresses build up to a critical point at which a crack is formed. Thermal cracks can.
