High Friction Surface Treatment



Crashes on the nation's roadways continue to be one of the leading causes of fatalities and major injuries in the United States. Roughly one half of all fatal crashes occur at horizontal curves and intersections. It is often the case that vehicle speeds and curve geometry create a "friction demand" higher than what can be countered with standard pavement surfaces. Intersection crashes often occur when driver error creates an unexpected need for increased friction demand to dramatically reduce vehicle speeds. One low cost approach to address high "friction-demand" locations is the installation of a High Friction Surface Treatment (HFST).

Highfrictionsurface.net was developed by members of ATSSA's High Friction Surfacing Council to assist policymakers better understand the impact of friction demand on roadway safety and the role that high friction surface treatments can play to improve safety at high-risk locations. The site promotes the use of pavement friction management programs to collect friction data. When combined with crash data, friction data can unmask unsafe locations and assist agencies in prioritizing the use of effective speed countermeasures. We hope you find this information helpful in the ongoing effort to create a safer driving environment for all motorists.
