Alpha Stone® High Friction Surface Treatment (HFST) is pavement treatment that dramatically and immediately reduce crashes, injuries, and fatalities associated with friction demand issues, such as:
Vehicles have different friction demands depending on the characteristics of the roadway. For example, a vehicle traversing a horizontal curve requires a greater level of friction than vehicles on a straight section. Common locations that require higher friction values are horizontal curves, steep grades, or intersection approaches. As a result of the increased friction demand, the roadway surface at these locations often becomes prematurely polished, reducing the pavement friction and contributing to highe
