CASE STUDY NATIONAL

In 2013, the State of Kentucky recognized that improvements needed to be made to the road infrastructure in order to reduce the number of roadway departures/run-off road crashes. Kentucky’s rural, mountainous terrain can be problematic for many drivers and the Kentucky Transportation Cabinet wanted to address these safety concerns.

After reviewing a variety of low-cost safety options in both wet and dry conditions, the KYTC (Kentucky Transportation Cabinet) started an initial program to improve skid resistance on roads by using high friction surface treatment. The program proved to be successful, showing a 69% decrease in skid-related crashes and fatalities on roadways treated with HFST.

This resulted in a statement program at over 75 location (2010) to improve pavement friction. Sites were selected based on crash data analysis to ensure appropriate placement.
