This test method covered the procedure for measuring paved surface frictional properties as a function of speed using the Dynamic Friction Tester (DF-Tester).
Formerly under the jurisdiction of Committee E17 on Vehicle-Pavement Systems, this test method was withdrawn in March 2018 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
1.1 This test method covers the procedure for measuring paved surface frictional properties as a function of speed using the Dynamic Friction Tester (DF-Tester).
1.2 The DF Tester consists of a horizontal spinning disk fitted with three spring loaded rubber sliders which contact the paved surface as the disk rotational speed decreases due to the friction generated between the sliders and the paved surface. A water supply unit delivers water to the paved surface being tested. The torque generated by the slider forces measured during the spin down is then used to calculate the friction as a function of speed.
1.3 The DF Tester can be used for laboratory investigations and in the field on actual paved surfaces.
1.4 The values stated in SI (metric) units are to be regarded as standard. The inch-pound equivalents are rationalized, rather than exact mathematical conversions.
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.`
