Encouraging Results of International Friction Measurement Harmonization through Quality Assurance and Calibration
Résumé
The friction measurement devices being used today in accordance with various international standards for the assessment of surface conditions on highways and runways are numerous. Although among the different equipment designs there are only a few substantially different measurement principles, they all have a significant number of design and operational differences. The difficulty of correlation and harmonization between the friction measurement systems due to these design variations has led to operator and regulatory governmental concerns regarding the viability of high-quality harmonized measurements collected by the large array of devices. This paper presents the work performed and the results obtained in the 1st European Pavement Friction Workshop to overcome the differences of designs and technical specifications of device subcomponents using unified standardization practice and uniform requirement/compliance checks and quality assessment of devices. The work also evaluated, analyzed and validated the European and US developed methodologies and technical solutions for standardization and the practical procedures for calibration and quality assessment to ensure reliable, quality data from all devices in a common scale.
