Tests were conducted by U S Army Engineer Waterways Experiment Station to determine minimum soil strength requirements for "go", compare experimentally determined with predicted strength requirements, and investigate interrelations of repetitive traffic of vehicles with heavy wheel loads and soil strength; vehicle performance on 50-pass basis was found to be related to rating cone index of 9 to 15 in. layer, i.e., critical layer; experimental vehicle cone indexes (VCI's) were determined and compared to VCI's computed by original and revised mobility index formula; latter produced VCI's that compared more favorably with experimental VCI's than those produced with original formula.
