WebJul 19, 2024 · Asphalt content correction factor—Asphalt binder content results may be affected by the type of virgin aggregate and RAP material in the mixture and the ignition furnace. The asphalt binder correction factor is calculated from the difference between the actual and measured asphalt binder contents for each sample.

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.
