The bulk specific gravity test is used to determine the specific gravity of a compacted HMAsample by determining the ratio of its weight to the weight of an equal volume of water. The bulk specific gravity test measures a HMA sample’s weight under three different conditions (Figure 1): 1. Dry (no water in sample). 2. … See more Specific gravity is a measure of a material’s density (mass per unit volume) as compared to the density of water at 73.4°F (23°C). Therefore, by definition, water at 73.4°F … See more The following description is a brief summary of the test. It is not a complete procedure and should not be used to perform the test.

WebMay 6, 2024 · 1.1 This test method covers the determination of bulk specific gravity and density of specimens of compacted asphalt mixtures. 1.2 This test method should not be used with samples that contain open or interconnecting voids or absorb more than 2.0 % of water by volume, or both, as determined in 11.3 . WebThus, all mix design methods use density and voids to determine basic characteristics of the asphalt mix (AASHTO TP4).Two different measures of densities are typically taken: (i) bulk specific gravity, G mb and (ii) theoretical maximum specific gravity, TMD.
