ABSTRACT:
Method for measuring resistance to slippage comprising the steps of mounting a sample of rubber at the bottom of a pendulum freely swinging on a shaft, sliding the sample of rubber along a road surface sample which is either dry or wet during swinging of the pendulum, measuring kinetic energy loss of the pendulum due to sliding of the sample thus obtaining resistance to slippage, in combination with the step of either heating or cooling the sample of rubber to a predetermined temperature for performing the method.
