    Significance and Use

    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.

    1. Scope

    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.
