Significance and Use | ||||||||||||||
The maximum specific gravities and densities of bituminous paving mixtures are intrinsic properties whose values are influenced by the composition of the mixture in terms of types and amounts of aggregates and bituminous materials. They are used to calculate values for percent air voids in compacted bituminous paving mixtures. They provide target values for the compaction of paving mixtures. They are essential when calculating the amount of bitumen absorbed by the internal porosity of the individual aggregate particles in a bituminous paving mixture. Note 2—The personnel and equipment used in performing this test can be evaluated in accordance with Practice D3666. |

1. Scope | ||||||||||||||
1.1 This test method covers the determination of maximum specific gravity of 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 other units given may be approximate and are given to help the user interpret units on available standard equipment used with this test method. 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. |
