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 (23°C) has a specific gravity of 1. See more The following description is a brief summary of the test.
