This method of test covers the determination of bulk specific gravity (Gmb) of specimens of compacted hot mix asphalt (HMA). This method should not be used with samples that contain open or interconnecting voids or absorb more than 2.0 percent of water by volume@ as determined in Sections 7.2 or 10.2 herein. If the sample contains open or interconnecting voids or absorbs more than 2.0 percent of water by volume@ then T 275 or T 331 should be used. The bulk specific gravity (Gmb) of the compacted HMA may be used in calculating the unit mass of the mixture. Note 1 - The values for bulk specific gravity (Gmb) obtained from T 275 or T 331 may differ. Care should be exercised when comparing test results from T 275 and T 331. 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 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.
