Standard Test Method for Theoretical Maximum Specific Gravity and Density of Bituminous Paving Mixtures

SIGNIFICANCE AND USE
The theoretical maximum specific gravities and densities of bituminous paving mixtures are fundamental properties whose values are influenced by the composition of the mixture in terms of types and amounts of aggregates and bituminous materials.
5.1.1 Maximum specific gravity is used (1) in the calculation of air voids in the compacted bituminous paving mixture, (2) in calculating the amount of bitumen absorbed by the aggregate, and (3) to provide target values for the compaction of paving mixtures.
SCOPE
1.1 This test method covers the determination of the theoretical maximum specific gravity and density of uncompacted bituminous paving mixtures at 25°C (77°F).
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 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 limitations prior to use.
