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 D 3203, 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 and 150 mm diameter cylindrical as well as cubical asphalt specimens to correct for absorptive and open graded mixes. Mixes such as Stone Matrix Asphalt (SMA), porous friction coarse, and Superpave coarse graded mixes with significant surface texture and interconnected voids should be sealed for accurate bulk specific density results. Follow manufacturer recommendation for appropriate bag sizes to be utilized with cubical and abnormally shaped samples.4

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 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.
