This report is a summary of the work conducted by the U.S, Naval Civil Engineering Research and Evaluation Laboratory in relating the external performance of off-the-road vehicles to measurable characteristics of the terrain. The importance of the shear strength of the soil to its ability both to support vehicle loadings and to allow the creation of tractive effort for the propulsion of the vehicle has motivated consideration of a portable, direct shear apparatus as a trafficability instrument. Presented herein is a possible form of such an apparatus and an approach to performance prediction made possible by its utilization. Over-all success in achieving the ultimate objective of reliably estimating the soft ground performance of vehicles by these methods and techniques will depend upon continued theoretical development of the fundamental relationships between soil and vehicles.
