(Test Method)Standard Test Method for Bulk Specific Gravity and Density of Compacted Bituminous Mixtures Using Automatic Vacuum Sealing Method
Standard Test Method for Bulk Specific Gravity and Density of Compacted Bituminous Mixtures Using Automatic Vacuum Sealing Method
SIGNIFICANCE AND USE
The results obtained from this method can be used to determine the unit weight of compacted bituminous mixtures and in conjunction with Test Method D3203, to obtain percent air voids. These values in turn may be used in determining the relative degree of compaction.
Since specific gravity has no units, it must be converted to density in order to do calculations that require units. This conversion is made by multiplying the specific gravity at a given temperature by the density of water at the same temperature.
This method can be used for 100 mm [4 in.] and 150 mm [6 in.] diameter cylindrical as well as cubical asphalt specimens to correct for inconsistencies in sample weight determinations resulting from drainage of water from samples and inaccuracy in saturated surface dry weight of absorptive coarse and open graded mixes. Mixes such as Stone Matrix Asphalt (SMA), porous friction course, and coarse graded mixes with significant surface texture and interconnected voids can be tested with this method. Follow manufacturer recommendation for appropriate bag sizes to be utilized with cubical and abnormally shaped samples.
Note 1—The personnel and equipment used in performing this test can be evaluated in accordance with Practice D3666.
SCOPE
1.1 This test method covers the determination of bulk specific gravity of compacted bituminous mixtures by the vacuum sealing method.
1.2 This method can be used for compacted cylindrical and cubical bituminous laboratory and field specimens.
1.3 The bulk specific gravity of the compacted bituminous mixtures may be used in calculating the unit weight of the mixture.
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalent; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.5 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 requirements prior to use.
