How do you calculate specific gravity of asphalt?

2020-6-28  How do you calculate specific gravity of asphalt? The basic premise of the maximum specific gravity is to divide the mass of the sample by the volume of the sample excluding the air voids. The mass is determined by measuring the dry mass of the sample either at the beginning of the test or after it has been dried at the end of the test.
