Standard Test Method for Determining Field VMA Based on the Maximum Specific Gravity of an Asphalt Mixture (G
1.1 This test method is intended to be used for a rapid field determination of voids in mineral aggregate (VMA) of asphalt mixture. It provides equations for calculating the VMA based on the asphalt content of the mix and its maximum specific gravity (Gmm). It is intended that this should be used for the rapid “field” determination of VMA during quality control (QC) operations at HMA plants, particularly where the specific gravity of the aggregate is highly variable.
Note 1: VMA determined using the rapid field method is VMA that has been corrected for aggregate absorption.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International StandardDetails, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
