This Technical Specification describes a method for determining the skid resistance of paved surface by measurement of the longitudinal friction coefficient µSkid.
The method provides a measure of the wet skid resistance properties of a bound surface by measurement of the longitudinal friction coefficient using a locked wheel with a slip ratio of 0 % (locked wheel: standard), or a slip ratio of (14 +- 1) % and a controlled speed. The test tyre is dragged over a pre-wetted pavement under controlled load and constant speed conditions while the test tyre is parallel to the direction of motion and to the pavement.
This Technical Specification covers the operation of the Skiddometer, Type BV 8, used in Switzerland.
