A road was constructed and tested for the US Department of Agriculture Forest Service and the US Department of Transportation Federal Department to qualify the effect of lowered tire pressure on road surfacing materials. The various surfaces were constructed of either a native soil, crushed aggregate, or asphalt concrete. Test traffic was applied with loaded (80,000 lb) and unloaded log trucks, one operating at conventional high tire pressure (100 psi) and the other at approximately 45 psi tire pressure. This report presents the background, design, construction procedure, and performance of the various sections during traffic. Keywords: Aggregate surfaced, Asphalt surfaced, Pavement maintenance, Pavement performance, Tire pressure. (sdw)
