LABORATORY EVALUATION OF AGGREGATES, AGGREGATE BLENDS, AND BITUMINOUS MIXES FOR POLISH RESISTANCE

The objectives of this research were to develop laboratory tests for preevaluating aggregates and paving mixtures to predict skid resistance properties in the field and to identify mixture designs incorporating optimum skid resistance and polish resistance. Laboratory evaluation methods developed include a circular-track machine using small-diameter pneumatic tires and a petrographic method for evaluating polish susceptibility based on percentage of hard mineral found in aggregate thin sections. Evaluation of the 2 test procedures is provided, and findings are given of laboratory tests on polish resistance properties of aggregates, aggregate blends, and bituminous mixes.
