This method covers the determination of bulk specific gravity 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 of the compacted HMA may be used in calculating the unit mass of the mixture. The values stated in SI units are to be regarded as the standard. This standard may involve hazardous materials@ operations@ and equipment. This standard does not purport to address all of the safety concerns@ if any@ associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
