Fact Sheet: The Safety EdgeSM is a proven technology that shapes the edge of a paved roadway at approximately 30 degrees from the pavement cross slope during the paving process. The Safety EdgeSM eliminates tire scrubbing, a phenomenon that contributes to losing control of a vehicle when trying to reenter onto the travel way. It has been successfully constructed on both asphalt and concrete pavements. The Safety EdgeSM has minimal impact on project cost combined with the potential to improve pavement life.
