Abstract:

Over time, the pavement surface may become polished, thereby reducing the available pavement friction and creating a higher risk of crashes. Also, intersections are locations where friction demand is higher due to slowing, stopping, and turning actions that require an adequate supply of friction. High Friction Surface Treatment (HFST) consists of a layer of durable, anti-abrasion and polish-resistant aggregate (typically calcined bauxite) over a thermosetting polymer resin binder that “locks” the aggregate in place to restore or enhance friction and skid resistance. HFST is one of the FHWA Proven Safety Countermeasures, and has been shown to significantly reduce injury and fatal crashes by roughly half at horizontal curves and nearly two-thirds at interchange ramps. As a result, agencies are applying HFST at intersections as well.
