Abstract:This TechBrief summarizes an evaluation of the effects of the Federal Highway Administration’s (FHWA’s) investment in high friction surface treatments (HFST) research, the availability and quality of such research, the deployment of the technology, and the safety impacts of HFSTs in the United States. HFSTs are high-quality aggregates that can be applied to existing or potential high crash areas to immediately and dramatically reduce specific crash types and their related injuries and fatalities.
