Description:

HFST is a pavement surface treatment consisting of a polymer resin binder used to bond a 1‒3 mm nominal-size polish- and abrasion-resistant aggregate to the pavement surface. HFST is a safety treatment used specifically to restore or enhance the friction of virtually any pavement surface in order to reduce roadway departure crashes. HFST provides a level of friction generally not achievable with conventional paving materials and sustains this high level of friction over time. HFST friction is provided through exceptional microtexture of the aggregate particles and high macrotexture of the finished surface.
