Safety

Roadway departures account for over half of all fatal crashes, some of which could have been prevented if a vertical pavement edge drop-off had not been present. Drop-offs occur when there are height differences between a paved road and the adjacent graded material. Conventional paving techniques result in vertical or nearly vertical pavement edges, which can cause safety concerns when they are exposed.

A cutting-edge technology known as the SafetyEdge℠ is a treatment that minimizes drop-off-related crashes. With this treatment, the pavement edge is sloped at an angle of 30 degrees to reduce the resistance of the tire remounting the drop-off. The reduced resistance is intended to allow a more controlled reentry onto the traveled way.
