    Abstract: A friction tester is provided which can measure the friction provided by a surface at a slip speed independent to the speed of travel of the friction tester. The friction tester comprises a vehicle which can travel over a surface at a first speed, and a test element which is driven to a second speed, and a measuring device, wherein the second speed is independently controllable; test element is engaged with the surface; and the first and second speeds are different so that the test element slips over the surface with a slip speed.
