Rutting

Permanent deformations of the pavement (indentations) in the wheel paths. Most common in intersections, where there is braking and stopping traffic.

Causes

• Heavy trucks
• Slow, stopping & standing traffic
• Poor aggregate
• Temperature susceptible asphalt
• Poor construction
• Moisture damage
• Post- construction compaction by traffic
