The Minnesota Road Research project (Mn/ROAD) is a comprehensive pavement research project. It consists of a mainline transition roadway to carry live Interstate traffic, and a low volume closed loop road used for controlled truck testing. A total of more than 4500 electronic sensors are embedded in the forty 150m-long pavement sections with each section having unique design. This paper describes a preliminary theoretical study of vehicle dynamic response for a wide range of pavement roughness obtained from Mn/ROAD pavement sections. The theoretical study was based on a quarter-car model. The purpose of this paper was to theoretically compare the relative vehicle dynamic response for a wide range of road roughness.
