1.1This test method covers the measurement of the frictional properties of winter-contaminated pavement surfaces using an averaging-type spot measuring decelerometer. If a data phone is used, it should meet all the requirements where the word decelerometer is used in this standard. The method produces a reading that is proportional to the deceleration sustained by a test vehicle fitted with pneumatic rubber tires braking with all wheels locked. A friction index for a section of winter-contaminated pavement is determined from the average of several deceleration measurements recorded over the section of winter-contaminated pavement.

1.2This test method is applicable to averaging-type spot measuring decelerometers.

1.3This test method is applicable to the following winter-contaminated pavement surface conditions:

1.3.1Ice;

1.3.2Wet ice (ice covered with a thin film of moisture of a depth insufficient to cause hydroplaning);

1.3.3Compacted snow, any depth;

1.3.4Slush on ice, slush not exceeding 3 mm (0.1 in.) in depth;

1.3.5Loose, dry snow, not exceeding 25 mm (1 in.) in depth;

1.3.6Ice control chemical solution on ice; and

1.3.7Sand on ice.

1.4This test method shall not be used when the following winter-contaminated pavement surface conditions are present:

1.4.1Water on a bare pavement surface;

1.4.2Slush; and

1.4.3Loose snow exceeding 25 mm (1 in.) in depth.

1.5The values stated in SI units are to be regarded as the standard. The values in parentheses are in inch-pound units and are not exact equivalents; therefore, each system must be used independent of the other, without combining values in any way.

1.6This 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.

1.7This 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.
