Pavement Friction

Continuous Pavement Friction Measurement (CPFM)

The friction provided by a roadway surface affects how vehicles interact with the roadway. Measuring, monitoring and maintaining pavement friction can prevent many roadway departure and intersection related crashes, resulting in fewer serious injuries and fatalities.

More than 50 years...

Friction Management

The main purpose of a pavement friction management program is to minimize friction-related vehicle crashes by:

  • Ensuring that new pavement surfaces are designed, constructed, and maintained to provide adequate and durable friction properties;
  • Identifying and correcting...

High Friction Surface Treatments (HFST)

High friction surface treatments (HFST) are pavement treatments that dramatically and immediately reduce crashes, injuries, and fatalities associated with friction demand issues, such as:

  • A reduction in pavement friction during wet conditions, and/or
  • ...
