Road and airfield surface characteristics - Part 12: Procedure for determining the skid resistance of a pavement surface using a device with longitudinal controlled slip: the BV 11 and Saab friction tester (SFT)

This technical specification establishes a standardized methodology for assessing surface friction on road and airport pavements. It specifically details the procedures for utilizing measurement equipment equipped with wheels capable of variable longitudinal slip ratios. The document outlines operational protocols for two distinct systems, namely the BV 11 device and the SAAB Friction Measurement System, ensuring consistency in data collection and interpretation. By defining precise test conditions and analytical approaches, the text facilitates the reliable evaluation of grip characteristics under controlled parameters. This approach supports uniformity in pavement safety assessments across different regions. The guidance provided allows technical personnel to execute friction tests with a high degree of reproducibility, contributing to a systematic understanding of pavement texture and its impact on vehicle control. It serves as a reference for generating comparable friction values, which are essential for maintaining infrastructure safety standards without relying on subjective observations.
