1.1 ,This test method is intended to be used for a rapid field determination of voids in mineral aggregate (VMA) of hot mix asphalt (HMA). It provides equations for calculating the VMA based on the asphalt content of the mix and its maximum specific gravity (G_mm). 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.
