What causes raveling in asphalt?

Raveling is the disintegration of an asphalt road surface. It is due to the dislodgment of the aggregate materials (gravel, sand, and crushed stone). It reduces skid resistance, roughens the road surface, and exposes the layers underneath to further deterioration.

Why do asphalt streets often have cracks in them?

The cracks form due to the forces applied by turning or braking motion of vehicles. Distortions in an asphalt pavement are caused by instability of an asphalt mix or weakness of the base or subgrade layers. These distresses may include rutting, shoving, depressions, swelling and patch failures.

The cracking patterns caused are extremely distinctive and resemble the scales on a reptile's back or the cracking you'd see if you dropped a hard-boiled egg.

What is reflective cracking in asphalt?

Reflective cracks occur due to breaks or cracks in underlying layers because of movement at the original crack. At this location, stresses concentrate and a crack propagates and reflects to the pavement surface over time.
