Trafficability Tests with Jumbo Truck on Organic and Coarse-Grained Mineral Soils
Abstract
Trafficability tests were conducted in soft muck and clean sand to determine the performance characteristics of the Jumbo, a 5-ton (M704) 4x4 truck fabricated from commercially available parts and equipped with large construction-equipment-type tires. Performance in muck, measured in terms of minimum soil strength in the critical layer required for 40 to 50 passes of the vehicle (vehicle cone index), was compared with its predicted performance computed from the WES mobility index formula for determining vehicle cone index of wheeled vehicles in fine-grained soils. Performance in the critical layer, was compared with the performance of an M135 2-1/2-ton 6x6 truck.
