Standard Test Method for Measuring the Skid Resistance of Pavements and Other Trafficked Surfaces Using a Walking Speed Continuous Friction-Measuring Equipment (CFME) Fixed-Slip Technique

Importancia y uso:

5.1 Walking speed CFME is used to measure skid resistance on pavements/sidewalks, roads, repaired pavements, horizontal pavement markings, helidecks, and other trafficked surfaces.

5.2 Walking speed CFME is designed for low-speed surface friction surveys.

5.3 Walking speed CFME does not require acceleration or deceleration areas. Friction surveys begin from a standing or rolling start.

5.4 Walking speed CFME can work in very close proximity to people and obstacles.

5.5 The Specification E1844 measure tire is a smooth tire that is mounted on walking speed CFME. A new ASTM tire standard is required for alternate tires designed for use on walking speed CFME. ASTM tire standards shall be entered in the referenced documents section of this standard.

5.6 Walking speed CFME can be specialized to operate in specific areas, such as helidecks, with a specialized software application for a specific surface area. See Fig. 1.

5.7 The field calibration/field test equipment, if required, should be contained within a transport case, readily available for field use. See Fig. 2.
