| Nosaukums | This Technical Specification describes a method for determining the skid resistance of a surface by measurement of the longitudinal friction coefficient LFCN. The method provides a measure of the wet skid resistance properties of a bound surface by measurement of the longitudinal friction coefficient using a continuous reading braked wheel fixed-slip device. The test tyre is dragged, parallel to the direction of motion and perpendicular to a pre-wetted pavement under controlled speed conditions. This document covers the operation of the BV11 and SAAB Friction Tester (SFT) with a fixed slip ratio of 17 %. Machines conforming to the general characteristics of the BV11 and SAAB Friction Tester and with the specific provisions of this document may also be used for the tests. |
