This British Standard describes a method for determining the wet-road skid resistance of a surface using the sideway-force coefficient routine investigation machine (SCRIM). The method provides a measure of the wet-road skid resistance properties of a bound surface by measurement of sideway-force coefficient at controlled speed. The method has been developed for use on roads but is also applicable to other paved areas such as airport runways.<\/p>\n
