Standard Test Method for Testing Side Force Friction on Paved Surfaces Using the Mu-Meter
|Publication Date:||1 August 2009|
|ICS Code (Road construction materials):||93.080.20|
This test method covers the measurement of the side force friction of paved surfaces utilizing a device commonly called a Mu-Meter.2
This test method utilizes a measurement obtained by pulling the Mu-Meter, containing two freely rotating test wheels angled to the direction of motion, over a pavement surface at a constant speed while the test wheels are under a constant static load. This method provides data of the side force friction (and other data) along the whole length of the test surface being tested which is applied to a variety of computerized algorithms enabling the production of results, including (but not limited to) rolling averages, numeric and graphical representations, friction mapping, and reports formatted in the layout approved by a wide variety of national airport regulators.
The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
