This Technical Specification describes a method for determining the wet-road skid resistance of a surface by measuring the LFCRNL using the Road Analyser and Recorder of Norsemeter (ROAR). In addition to the friction measurement also measurements of pavement texture can be performed. The method provides friction coefficient measurements of pavements by using a hydraulically braked test wheel at a pre-set slip ratio, which can be fixed from 5% to 95%. Default value for the Netherlands is 86 %. The standard test tyre is dragged over a pre-wetted pavement under controlled load and speed conditions while its running direction is parallel to the direction of motion and perpendicular to the pavement. To determine the macro texture of the pavement a laser system is used. This system is placed in front of the towing vehicle in order to measure the macro texture on dry pavements and on the same path as the skid resistance measurement is done. The standard for this measurement and the used measuring device are well described in standard EN ISO 13473-1 and EN ISO 13473-2.
