An aggregate blend is composed of 53% coarse aggregate by weight
(sp. gr. 2.702), 43% fine aggregate (sp. gr. 2.621), and 4% filler
(sp. gr. 2.779)/ the compacted specimen contains 6% asphalt binder
(sp. gr. 1.052) by weight of total mix, and has a bulk density of
145.2 lb/ft3. ignoring
absorption, computer the percent voids in total mix, percent voids
in mineral aggregate, and the percent voids filled with asphalt.
