ABSTRACT
The term skidding resistance refers to the extent to which the road contributes to friction and typically refers to wet conditions. It is measured and predicted in a number of different ways. These all involve sliding some form of rubber over a wet surface and measuring the forces developed under a known load. Frictional resistance is used to describe these forces that resist motion when the two surfaces are in contact. A coefficient of friction is defined as the force resisting motion divided by the vertical load. For a road surface, the force resisting motion is developed between a vehicle tyre and the road surfacer.
