• Abstract:
  This report describes the installation of Tyregrip(R), a high friction surface, on a high crash location to reduce crash rates. Tyregrip(R) 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(R) has improved the friction properties of the crash prone ramp. The study was terminated in May of 2016 due to the delamination of the Tyregrip(R) high friction surface after a service life of five years. The friction resistance of the (R) remained in the low to high 70’s throughout the five year evaluation period. The wet surface crash rate was reduced by 79% as compared to the five years prior to the installation of the Tyregrip(R). It was concluded that Tyregrip(R) is a viable mitigation strategy for roadways with high rates of run-off-the-road crashes. It was recommended that Tyregrip(R) and other high friction surface treatments be considered for locations with high rates of wet weather run-off-the-road crashes.
