Specific gravity of asphalt concrete
WebSamples are compacted with N des gyrations for the initial stage of determining the design aggregate structure. The volumetric properties are determined by measuring the bulk specific gravity (G mb) of compacted mixtures and the maximum theoretical specific gravity (G mm) of loose mixtures with the same asphalt content and aggregate … WebA compacted asphalt concrete specimen has the following properties:a. Asphalt content = 5% by total weight of the mixb. Bulk specific gravity of the mix = 2.500c. Theoretical maximum specific gravity = 2.610d. Bulk specific gravity of the aggregate = 2.725 Ignoring absorption, compute the percents VTM, VMA, and VFA.
