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, computethe percent voids in total mix, percent voids in mineral aggregate, and thepercent voids filled with asphalt.
