ASTM D3203-05
(Test Method)Standard Test Method for Percent Air Voids in Compacted Dense and Open Bituminous Paving Mixtures
Standard Test Method for Percent Air Voids in Compacted Dense and Open Bituminous Paving Mixtures
SIGNIFICANCE AND USE
The percent of air voids in a bituminous mixture is used as one of the criteria in the design methods and for evaluation of the compaction imparted in bituminous paving projects.
SCOPE
1.1 This test method covers determination of the percent air voids in compacted dense and open bituminous paving mixtures.
1.2 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.
