TRAFFICABILITY OF SOILS. TESTS ON COARSE GRAINED SOILS WITH SELF-PROPELLED AND TOWED VEHICLES 1958-1961
Abstract
Standard and special vehicle tests were conducted with 21 military vehicles over a range of vehicle weights, tire pressures, and sand strengths and conditions to pursue investigations recommended in the 15th Supplement of this series. Standard tests were of three kinds: self-propelled, tow ing, and towed. Special tests included tests on: honeycomb sand; gravel beaches; drawbar pull-slip; a truck-trailer combination; the effects of a traction device, tire tread, and wheel load; and the Airoll. Coarse-grained soil tests were made in five locations in the United States and France. Principal conclusions were that: (a) maximum towing force of self-propelled wheeled vehicles on level sand (for the same sand and vehicle con ditions) was about 2% greater than maximum slope negotiable, and these data can be correlated; (b) vehicle performance tended to improve with de creasing contact pressure; (c) 6x6 vehicles gener ally had higher tractive coefficients than 4x4 vehicles with the same contact pressure on the same sand conditions; and (d) vehicle performance on wet sand that tended to liquefy under the vehicle load was similar to that on fine-grained soils.
