WVirginia Highway & Transportation Research CouncilUS Transportation CollectionLaboratory data were gathered with a newly developed stripping test in anticipation that the test would be adopted for use by the Department. In addition to providing experience in the performance of the test and interpretation of test results, the investigation was designed to give a determination of whether there were significant differences in the brand of asphalt cements and antistripping additives used as reflected by their influence on the bond between the asphalt and aggregate in the mixtures tested. The results of tests on mixes containing aggregates from eight sources, three asphalt cements, and two antistripping additives in various combinations indicated a significant difference for the additives but none for the asphalts. Results of a supplementary investigation indicated that the test method might be modified so that it can be performed with equipment already available within the district materials laboratories
