    HFST is an innovative technique to improve the safety of drivers at high-priority crash locations throughout the commonwealth. Road surfaces become polished in areas where drivers brake often, like going around curves, down steep roads, or at an intersection. This makes vehicles skid more because there is less friction between the tires and the road surface. Wet road surfaces can also reduce pavement friction and cause skidding or hydroplaning.

    HFST is added to the top of a road surface, using materials, such as bauxite, to create more friction on pavement. These materials, called aggregates, are high quality and are less likely to wear down than normal pavement. Having greater friction helps to keep vehicles in their lane on slippery pavement around curves and helps the driver to stop.

    Please use caution if traveling through the area. Work zone safety is everyone’s responsibility.
