Optimizing Continuous Friction Testing on Low-Speed Roads and in Tight Curves

Ohio Department of Transportation (ODOT) performs friction testing to determine whether the roadway has sufficient available wet friction to promote safety during wet conditions. Currently, ODOT relies on the locked wheel friction testing method, which has long been accepted on roadway segments as a validation of available friction. Due to the "locked" wheel, the application of this method is limited in situations where speeds are at 20mph or the roadway is curved. As a result, ODOT relies on visual inspection of the area to determine if a friction problem exists. The goal of this research is to identify and validate a process or technology that can provide accurate, reliable and repeatable friction testing at slow speeds (e.g., at 20mph) and in tight curves.
