Abstract
In a rubber friction test method of measuring a friction coefficient of a rubber test specimen by relatively moving the rubber test specimen and a test road surface in a state in which the rubber test specimen is pressed to the test road surface by applying a load, the method includes a step of measuring a resistance force acting on the rubber test specimen while accelerating or decelerating a speed of the relative movement, and a step of calculating the friction coefficient based on the applied load and the measured resistance force.
