Cracks are caused by deterioration of the pavement. Obviously, pavement is best when it is first constructed. As sunlight oxidizes the pavement and seasonal temperature changes expand and contract the pavement, cracks form. Water, impurities, and debris infiltrate the cracks and continue to degrade the pavement and put the pavement’s subbase at risk.

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.

Those Cracks on the Edge of the Road …What Causes Them?

As the crack gets longer it eventually turns toward the outer edge of the pavement, making the characteristic "C" shape. It doesn't turn inward because the pavement is more resistant to cracking in that direction. It doesn't run parallel to the pavement edge because at some point the support gets stronger, and so the crack turns outward.
