WebJan 1, 2016 · The bulk specific gravity ( Gmb) of the compacted asphalt mixture may be used in calculating the unit mass of the mixture. Note 1 -The values for bulk specific gravity ( Gmb) obtained from T 275 or T 331 may differ. Care should be exercised when comparing test results from T 275 and T 331. 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).
