Types of Asphalt Pavement Cracks and Distresses

1. Fatigue Cracking (Alligator Cracking): Interconnected cracks caused by repeated traffic loading and structural weakness.

2. Longitudinal Cracking: Cracks running parallel to the road centerline.

3. Transverse Cracking: Cracks running perpendicular to the road centerline, often caused by temperature changes.

4. Block Cracking: Interconnected cracks forming rectangular or square-shaped blocks.

5. Edge Cracking: Cracks developing along pavement edges due to inadequate support or drainage problems.

6. Reflection Cracking: Cracks appearing in asphalt overlays above existing cracks or joints in the underlying pavement.

7. Slippage Cracking: Crescent-shaped cracks caused by inadequate bonding between pavement layers.

8. Rutting: Permanent longitudinal depressions in wheel paths caused by deformation of pavement layers.

9. Raveling: Loss of aggregate particles from the asphalt surface due to inadequate binder or aging.

10. Potholes: Bowl-shaped holes resulting from pavement deterioration, often associated with water infiltration and traffic loading.

11. Bleeding (Flushing): Excess asphalt binder rising to the pavement surface, creating a smooth, shiny, and potentially slippery surface.

12. Depression: Localized low areas in the pavement caused by settlement or inadequate compaction.

13. Corrugation and Shoving: Waves or ridges formed by plastic movement of the asphalt pavement under traffic.

14. Diagonal Cracking: Cracks developing diagonally across the pavement, sometimes associated with localized stress or movement.
