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.
