Accurate determination of bulk specific gravity of compacted hot mix asphalt (HMA) samples is an important step in ensuring quality of asphalt pavements. A measurement of the mass and the sample volume are required to calculate the bulk specific gravity. Measuring the sample...
(2.2)Density(kg/m³)=(specificgravity)×997.6 Sometimes the plastic being measured is sensitive to water. Method B of ASTM D792 allows the use of other liquids. In that case the density of the liquid,d, is added to the calculation as shown inEq. (2.3): ...
This procedure covers the determination of the maximum specific gravity (G mm) of uncompacted hot mix asphalt (HMA) paving mixtures in accordance with AASHTO T 209-12. Two methods using two different containers – bowl and flask – are covered. Specimens prepared in the laboratory shall be ...
