Project description

Pavement friction testing is conducted by the Ohio Department of Transportation (ODOT) in accordance with ASTM E-274, "Standard Test Method for Skid Resistance of Paved Surfaces, using a Full-Scale Tire". The standard speed of testing in Ohio is 40mph. Due to safety concerns related to testing on cloverleaf ramps, roundabouts, curves, interstate, and divided highways ODOT would like to have the capability to collect friction data at a variety of speeds (i.e., 20mph, 40mph and 60mph). Research is needed to develop a repeatable methodology for collecting friction data while traveling at different speeds and correlating the new data to historical data that was collected at 40 mph. The goal of this study is to provide for a safer, multi-speed (20 mph,40 mph, and 60 mph) friction collection and correlation process.
