What Is High Friction Surfacing

It has been shown that approximately one quarter of highway fatalities in the United States occur at or near horizontal curves. Contributing factors to these run-off-the-road crashes include excessive vehicle speed, distracted driving, and driver error. At some locations, the deterioration of pavement surface friction may also be a factor, particularly during wet weather.

An emphasis will be placed on pavement surface treatments termed High Friction Surfacing or HFS, which utilize alternative materials such small-sized polish and wear-resistant aggregates bonded to the pavement surface using proprietary resin binders.

High Friction Surfacing (HFS), also known as anti-skid surfaces, are pavement surface treatment systems that are composed of tough polish-resistant, abrasion-resistant aggregates bonded to the pavement surface using a resin.
