Abstract: The Minnesota Department of Transportation in cooperation with the Federal Highway Administration and the Local Roads Research Board of Minnesota is constructing the Minnesota Road Research Project (MN/ROAD). This facility is being built on Interstate 94 (I-94) in the east-central part of the state. The MN/ROAD will have high-and low-volume traffic test sections. The low-volume sections will be constructed on a parallel access road, and will be trafficked artificially. Section designs call for the use of portland cement concrete, asphalt concrete, and aggregate surfaces. Different construction techniques will be tried and material problems will be intentionally built into some of the test sections. Special classifications for aggregate surface, base, and subbase materials will be used in the pavement sections. The natural subgrade in this area is primarily a frost susceptible loam. This combined with shallow water table depths and severe winter temperatures make this an ideal location for frost heave studies. A second type of subgrade will be imported for use in some of the low-volume sections. This soil will be a high-quality granular material.
