ASTM D6857-03

Standard Test Method for Maximum Specific Gravity and Density of Bituminous Paving Mixtures Using Automatic Vacuum Sealing Method

SCOPE
1.1 This test method covers the determination of maximum specific gravity of and density of uncompacted bituminous paving mixtures at 25C (77F).
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.
1.4 A multi-laboratory precision for this standard has not been developed at this time. This standard should not be used for acceptance or rejection of a material for purchasing purposes.
