DEVELOPMENT AND APPLICATION OF THE INTERNATIONAL FRICTION INDEX

The surface or roads must provide an adequate level of friction at the tire-pavement interface to ensure safe operation of vehicles. Methods and systems used throughout the world for measuring tire pavement friction vary greatly. The PIARC Technical Committee on Surface Characteristics conducted the international experiment to compare and harmonize texture and skid resistance measurement to develop a uniform method for reporting pavement friction. The overall objective of the experiment was to compare the many different measuring methods used around the world and to develop relationships for converting results produced by the different devices to a common scale, the International Friction Index (IFI). As a result, international standardization and harmonization can be achieved. The International Friction Index (IFI) consists of two parameters: F60 and Sp. These two parameters can be determined using data from a friction measurement and a texture measurement. (A) For the covering abstract see IRRD E100847.
