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.
Features
Rapid return to Service
With rapid 2 hour cure time after placement, even in conditions down to 40ºF
Superior Adhesion
Excellent adhesion to asphalt and concrete pavements
Restores Friction
Exceeds the requirements of most high friction surface treatment (HFST) specifications
Simple
Simplified stoichiometry reduces concerns with mix ratio. Can be applied with current automated installation equipment or can be mixed by hand for smaller high friction surface treatment installations.
