Abstract: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.
