What causes a pavement to crack?
Pavement with long transverse joint spacing may crack due to tensile stresses from temperature curling. Theoretical and practical studies of pavement have determined that the optimal spacing between joints depends on the slab thickness, subbase stiffness, and strength.
Early Cracking of Concrete Pavement - causes and repairs
The temperature and moisture gradient that exists between top and bottom of the pavement slabs causes the curling and warping of the slab. The natural response causes the pavement to crack at regular intervals.
