"The utilization of glass as an aggregate in asphaltic concrete pavements has been suggested as a means for reusing the increasing amounts of waste glass generated each year in the United States. Recent studies have shown that asphaltic mixtures containing glass aggregates can be designed to meet Marshall requirements for stability, flow and void content but the abrasiveness of mixtures containing glass aggregates had not been investigated. The objectives of this study were to develop a laboratory wear testing apparatus and compare the abrasiveness of asphaltic concrete mixtures using glass aggregates with the abrasiveness of mixtures using several different conventional aggregates.

Equipment and procedures were developed to assess the relative abrasiveness of laboratory prepared specimens and field specimens containing glass and conventional aggregates by spinning a rubber wheel on the specimen surface and measuring the resulting weight loss of the wheel. Based upon the results of the tests conducted, it was concluded that coarse glass particles cause more wear than limestone or gravel coarse aggregates while no difference in wear results when traprock coarse aggregates are replaced by coarse glass. Replacement of either limestone or traprock fine aggregate by fine glass in mixtures containing limestone coarse aggregate increased wear while no difference in wear results when fine glass substituted for river sand. However, in mixtures containing gravel coarse aggregate, fine glass causes more wear than river sand.

Since the effects of skid resistance and aggregate angularity upon wear were found to differ from effects reported in a previously published study of tire wear, it was concluded that the testing method developed might not accurately reflect differences in tire wear resulting from surfaces of varying composition. Modifications in the testing method to minimize abrasion of the specimen surface during testing are suggested"--Abstract, pages ii-iii.
