Evaluation of Tyregrip® High-Friction Surfacing

This report describes the installation of Tyregrip®, a high friction surface, on a high accident location to reduce accident rates. Tyregrip® is a thin polymer overlay system that uses a two part epoxy binder and calcined bauxite aggregate. Postconstruction friction resistance results in the middle to high 70’s indicate that the Tyregrip® has improved the friction properties of the collision-prone ramp.
The installation will be monitored for friction resistance and accident reduction for a minimum of five years.
