Incorporating Network-Level Friction Data into KYTC's Pavement Resurfacing Prioritization

Kentucky Transportation Cabinet (KYTC) identifies and prioritizes pavement resurfacing projects based on available friction data, but few pavements undergo friction testing. Historically, friction data have only been available through either the Cabinet’s polish-resistant aggregate certification process or at specific locations for which reviews have been requested. With KYTC’s network-level SCRIM testing, the agency can analyze relationships between friction properties, roadway geometry, and crash data. Using these data, pavement management staff can factor existing friction properties into the project prioritization process. But methods are still needed to incorporate friction properties into KYTC’s existing pavement evaluation process to improve safety on state-maintained roadways.
