Причина отмены This practice described a laboratory procedure for estimating the extent to which aggregates or pavement surfaces are likely to polish when subjected to traffic.

Formerly under the jurisdiction of Committee E17 on Vehicle-Pavement Systems, this practice was withdrawn in June 2022. This standard is being withdrawn without replacement due to its limited use by industry.

Значение и использование

4.1 The use of laboratory-obtained polishing curves and speed gradients on proposed aggregate combinations and pavement mixtures are helpful tools in predicting the polishing characteristics of these surfaces if placed in field service.

Область применения

1.1 This practice describes a laboratory procedure for estimating the extent to which aggregates or pavement surfaces are likely to polish when subjected to traffic. Specimens to be evaluated for polishing resistance are placed in a circular track and subjected to the wearing action of four small-diameter, pneumatic tires without use of abrasive or water. Terminal polish is achieved after approximately 8 h of exposure.

1.2 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.
