THE LONGITUDINAL TRACTION CHARACTERISTICS OF TRUCK TIRES AS MEASURED ON DRY PAVEMENTS
A mobile traction dynamometer has been constructed and applied in over-the-road measurements of the braking traction of truck tires. An experimental program is described in which a sample of heavy truck tires has been tested to provide baseline characterizations of the first-order sensitivity of 'slip' behavior to load, velocity, and pavement type. The overall findings are presented in the form of cross plots of 'peak' and 'slide' traction numerics while complete slip curves are presented in an appendix. The test machine, its operation, and the processing of the generated data are discussed in substantial detail.
