Bitumen specific gravity

WebMar 25, 2024 · The Specific Gravity of Bitumen defined as the ratio of mass of given volume of bitumen of known content to the mass of equal volume of water at 270C. The specific gravity can be measured using either Pycnometer or preparing a cube specimen of bitumen in semi solid or solid state. WebThis value is based on the asphalt mixture’s maximum specific gravity – also known as the Rice value or G mm in Superpave. The maximum unit weight is determined by multiplying the Rice value by 62.4 pounds per cubic foot (PCF). For example, 2.500 is a typical Rice value. 2.500 X 62.4 = 156.0 PCF. Then, if 95% compaction is specified, the ...
