An aggregate blend is composed of 59% coarse aggregate by weight (Sp. Gr.2.635), 36% fine aggregate (Sp. Gr. 2.710), and 5% filler (Sp. Gr. 2.748). Thecompacted specimen contains 6% asphalt binder (Sp. Gr. 1.088) by weight oftotal mix and has a bulk density of 2305 kg/m3. Ignoring absorption, compute the percent voids in total mix, percent voids in mineral aggregate, and the percent voids filled with asphalt.
A 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.
