Performance of Soils under Tire Loads. Report 8. Application of Test Results to Tire Selection for Off-Road Vehicles

摘要

Data from a very large block of previously collected data from laboratory single-wheel tests and from selected field tests were examined to: determine whether the dimensionless prediction terms for sand could be improved, and extrapolate laboratory relations to field relations for full-size vehicles. The basic prediction terms can serve as the base for predicting wheeled vehicle performance in the field if RCI (rating cone index) is substituted for C in the term for clay. Equations that describe the pertinent relations are examined in detail, and examples illustrate several of their many possible applications. (Author)
