Trafficability of Soils: Eighteenth Supplement, Development of Revised Mobility Index Formula for Self-Propelled Wheeled Vehicles in Fine-Grained Soils

The main purposes of this study were to (a) obtain adequate test data to determine experimentally the vehicle cone index (VCI) for 50 passes for vehicles mounted with nonconventional tires and (b) use results of the field tests to develop a revised mobility index (MI) formula for self-propelled wheeled vehicles.
