This method covers the determination of bulk specific gravity (Gmb) of specimens of compacted hot mix asphalt (HMA) mixtures.
This method should be used with samples that contain open or interconnecting voids and/or absorb more than 2.0 percent of water by volume, as determined by T 166. An agency may specify this method as an alternative to T 275.
The bulk specific gravity (Gmb) of the compacted HMA may be used in calculating the unit mass of the mixture.
Similar, but not identical, to ASTM D 6752/D 6752M-11e1.
