This report documents the results of a comprehensive series of laboratory tests for asphalt-aggregate mixtures which was part of the Project A-0034, 'Performance Related Testing and Measuring of Asphalt-Aggregate Interactions and Mixtures.' The compaction investigation focused on the extent to which the method of laboratory compaction (gyratory, kneading, and rolling wheel) affects fundamental mixture properties of importance to pavement performance in service. The compaction method was found to significantly affect properties of the dense-graded mixtures that were evaltuated. The kneading specimens were the most sensitive to aggregate characteristics and least sensitive to asphalt characteristics. Gyratory specimens were least sensitive to aggregate characteristics and only slightly more sensitive than rolling wheel specimes to asphalt characteristics. The rolling wheel compactor has been selected for use in subsequent phases of the SHRP project.
