High Friction Treatment (HFST)

February 10, 2016

High Friction Surface Treatments (HFST) are thin layers of specially engineered material overlaid on the pavement of roadways to create a long-lasting skid resistant surface. HSFT is an extremely rough, hard, durable surface capable of withstanding everyday roadway demands, such as heavy braking. HFST restores pavement surface friction characteristics where traffic has worn down existing pavement surface aggregates at less than what it would cost to mill and resurface. HFST can also help compensate for inadequate geometric designs such as sharp curves and/or substandard or variable superelevations.

 

Crash data is used to identify high priority areas, where engineers determine that HSFT may help increase pavement traction in areas of critical braking and cornering maneuvers. One of the more notable locations of recent HFST applications is the Fairbanks curve in Orlando. HSFT was also recently added to the SR 417 ramp for eastbound I-4 to address lane departure crashes and will soon be added to the I-95/US-1 loop ramp for skid resistance.
