Standard Method of Test for Bulk Specific Gravity (Gmb) of Compacted Asphalt Mixtures Using Saturated Surface-Dry Specimens

          


               SCOPE

Ø  This method of test covers the determination of bulk specific gravity (Gmb) of specimens of compacted asphalt mixtures.

Ø  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 Section 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.

Ø  The bulk specific gravity (Gmb) of the compacted asphalt mixture may be used in calculating the unit mass of mixture.

Ø  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 result from T 275 or T 331.

 

Ø  The values stated in SI units are to be regarded as the standard.

 

Ø  This standard may involve hazardous materials, operations, and equipment. This standard does b not purport to address all the safety concerns, if any, associated with its used. 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.
