Edge Drop-off

An edge drop-off is road geometry defect where the vertical distance from the edge of seal to the adjacent shoulder exceeds acceptable limits.

Edge drop-offs generally occur when the road shoulder is worn, or there is inadequate strength of the pavement ay the edge of the roadway. A significant edge drop-off can make the transition between the road and its shoulder challenging particularly for smaller vehicles, and this may result in a loss of control for the vehicle.

Treatment Options
