FHWA HFST Information

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
• A high friction demand due to vehicle speed and/or roadway geometrics.

A research report published by the Federal Highway Administration (FHWA) shows HFST is estimated to reduce wet crashes by 83% and total crashes by 57%.
