Tampa Uses High-Friction Pavement To Reduce Crashes
It’s called a high-friction surface treatment and it’s a thin layer of high-quality polish-resistant aggregate bonded to the pavement surface with polymer resin binder, according to FDOT.
This high-friction pavement is already proving to be effective. FDOT put in the surface treatment at the State Road 60 (Memorial Hwy) ramp near Tampa International Airport. The ramp connects SR 60 Northbound to the Veterans Expressway.
Overall, the state saw the number of crashes cut by 67 percent. There was also a 73% reduction of wet weather crashes and 53% fewer run-off-the-road crashes.
According to FDOT, crash reduction has proven most effective on rural and urban horizontal curves and tight-radius loop ramps.
FDOT crews also applied the high-friction surfacing at busy intersections and downhill roads. Other scenarios include approaches to rail crossings, school crossings, and tolling areas.
