PPC HFST: High Friction Surface Treatment

PPC HFST, the polyester resin-based high friction surface treatment (HFST), is designed to improve the coefficient of friction to reduce crashes in horizontal curves and intersections.

High friction surface treatment is a cost-effective solution that dramatically and immediately reduces crashes, injuries, and fatalities.
