This method covers the determination of bulk specific gravity (Gmb) of specimens of compacted asphalt 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 AASHTO T 166. An agency may specify this method as an alternative to AASHTO T 275.
The bulk specific gravity (Gmb) of the compacted asphalt mixture may be used in calculating the unit mass of the mixture.
This standard was formerly designated as provisional standard TP 69.
