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.
