Laboratory evaluation of aggregates, aggregate blends, and bituminous mixes for polish resistance. Paper presented at the 53rd Annual Meeting of the Highway Research Board HRB, Washington, D.C., January 1974.

Workable methods to determine the wear and polishing properties of aggregates and bituminous paving mixtures in the laboratory are developed. It may be possible to improve marginal polish-resistant aggregates to an acceptable level by blending appropriate percentages of high "polish-resistant" aggregates.
