Road and airfield surface characteristics - Procedure for determining the skid resistance of a pavement surface using a device with longitudinal controlled slip (LFCN): ViaFriction (Road Analyser and Recorder of ViaTech AS) Ingestion-build-242630 2 mm and 81 Scope This Technical Specification describes a method for determining the wet road skid resistance of a surface by measurement of the longitudinal friction coefficientLFCN. The described method is also used to determine the skid resistance on a surface covered by ice or snow. The method provides friction coefficient measurements of the pavement by using an electrically braked test wheel. ViaFriction can operate in the following modes: Fixed slip:
