Standard Method of Test for
Bulk Specific Gravity and Density of Compacted Asphalt Mixtures
Using Automatic Vacuum Sealing Method
AASHTO Designation: T 331-081
ASTM Designation: D 6752-03e1
SCOPE
1.1.This method covers the determination of bulk specific gravity of specimens of compacted hot mix asphalt (HMA) mixtures.
1.2.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 I66. An agency may specify this method as an alternative to T 275.
1.3.The bulk specific gravity of the compacted HMA may be used in calculating the unit mass of the mixture.
1.4.The values stated in SI units are to be regarded as the standard.
