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.

Pavement Crack Sealing | CRAFCO

When pavement movement takes place due to temperature change or traffic loads, the crack filler is separated from the edge allowing water and incompressible materials to enter the crack and into the pavement. Crack filler does not achieve the same level of service life as crack sealant, and it does not preserve the pavement as long as crack sealant.
