适用范围：This Technical Specification describes a method for determining the skid resistance of a surface by measurement of the longitudinal friction coefficient LFCG. The method provides a measure of the wet skid resistance properties of a bound surface by measurement of the longitudinal friction coefficient using a continuous reading small braked wheel fixed-slip device. The test tyre is dragged over a pre-wetted pavement under controlled speed conditions while the test tyre is parallel to the direction of motion and perpendicular to the pavement. Test speeds can vary from 5 km/h to 130 km/h depending on the application. The measured values can be affected by the test speed. The method has been developed for use on paved areas such as roads and airport runways and can also be used indoors. This Technical Specification covers the operation of the Griptester: The GripTester is a device developed by Findlay Irvine Ltd in the United Kingdom that uses the braked-wheel fixed-slip principle with a small test wheel to make measurements of skid resistance continuously on airfields, roads and other surfaces. The fixed slip ratio is 15 %. A machine conforming to the general characteristics of the GripTester and the specific provisions of this Technical Specification may also be used for the tests. The skid resistance of a pavement is determined by friction measurements and measurements of pavement texture. Where measurement of pavement texture is required the standard for this measurement and the device is described in EN ISO 13473-1.
