ASTM WK40015

    Work Item: ASTM WK40015 - New Test Method for Determining the Skid Resistance of a Pavement Surface by Measuring the Sideway Force Coefficient (SFCS) Using SCRIM

    (What is a Work Item?)

    Developed by Subcommittee: E17.21 | Committee E17 | Contact Staff Manager



    1. Scope

    1.1 This test method covers the procedure for determining the wet-road skid resistance properties of a surface layer by measurement of sideway-force coefficient (SFCS) at a controlled speed. 1.2 This test method has been developed for use on roads but is also applicable to other paved areas such as airport runways. 1.3 This test method covers the operation of the SFCS routine investigation machine SCRIM. It uses the side force principle to make routine measurements of skid resistance continuously on long lengths of road. SCRIM test equipment has been built onto a number of different vehicle chassis and functions independently of vehicle choice. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

    This standard is needed as there is currently no ASTM standard covering this device. It will be used by the Department of Transport and other organizations that are involved in using SCRIM to carry out friction testing.
