MVMA/NHTSA/SAE Heavy Truck Round Robin Brake Test

This paper describes a Heavy Truck Round Robin Brake Test involving three test vehicles at ten different proving grounds. The purpose of the program was to evaluate the practicality and repeatability of the test procedure proposed by the ABS Test Procedure Task Force of the Heavy Truck Subcommittee of the Motor Vehicle Safety Research Advisory Committee to NHTSA and to compare surface friction characteristics of dry high Mu and wet low Mu (coal tar emulsion sealed) test surfaces at different proving grounds.
