"Pushing" and "Shoving" are deformations of the pavement surface. They are most common in intersections, where there is braking and stopping traffic. It is easiest to detect at intersections where transverse striping becomes "wavy".
"Delamination" are sections of a surface layer that have come loose from the pavement.
Causes
- Unstable Mix
- Braking, stopping, accelerating traffic
- Slippage between layers
- Poor interlayer bond
- Poor construction
- Heavy trucks
- Moisture damage
