Investigations have been conducted to study the design thickness and material requirements for roads in Minnesota. The Minnesota R-Value and AASHTO Interim Guide procedures were judged to be most appropriate for Minnesota cities and counties. A test plan has been devised to document the performance of low-volume roads. The parameters are pavement materials, embankment soil strength, inplace granular equivalent thickness, and traffic. These levels have been selected to establish a factorial design study. Sixty-five field sections have been established throughout the state. The sections selected have previously been tested with the Road Rater or Benkelman Beam and the traffic analyzed. The present field condition has been observed. The information should continue to be obtained to verify the performance relationships used for the AASHTO Interim Guide and the Minnesota R-Value Design Procedure.
