What is HFS Used For?

High friction surfaces are used primarily for restoring or enhancing the skid resistance of a pavement surface, but can also be used for lane delineation, bike paths, traffic calming, or for decorative purposes.  Areas where high friction or anti-skidding properties are desired, include:

  • Horizontal Curves and Ramps
  • Intersections/Intersection Approaches
  • Steep Grades
  • Roundabouts
  • Bus Stop Areas
  • Pedestrian Walkways
  • Bridge Decks
  • Pavement Surfaces Susceptible to Icing

Under the current FHWA HFS demonstration study, emphasis will be placed on evaluating the efficacy of HFS for improving skid resistance and reducing accidents at horizontal curves.
