PCC Surface Characteristics - Rehabilitation (MnROAD Study)

Research findings will enable the Minnesota Department of Transportation (Mn/DOT) to specify ranges of values for friction, ride, and texture that will optimize quietness, ride, texture and friction in program delivery. It will reduce the incidence of uncomfortable ride, hydroplaning, and obnoxious whines, with the results of this study benefiting.the average road user. Research outcomes will facilitate a family of curves and algorithms that will address the optimization for giving good friction, which unfortunately was interpreted by profilometers as pavement roughness, as well as noise and friction. The researchers will have a prediction of noise level, based on the grinding techniques. The project will provide data for optimization of pavement quietness, friction, texture and ride. The researchers note that they will be in a better position to improve their diamond grinding and texture specification, if necessary. Also, the project will address the question as to what degree of total noise is generated by tire-pavement interaction. Monitored over time, performance versus time characteristics will be obtained for various grinding techniques. This pooled fund study is strictly to perform the surface characteristics research on rehabilitated test sections at Minnesota Road Research Facility (MnROAD); its funding will come from Mn/DOT and other participating states. The funding for the rehabilitation of the test sections will be obtained separately from Mn/DOT and other partners.
