Compute the percent voids, percent voids in mineral aggregate
(VMA), and the percent VMA filled with asphalt in a compacted
mixture with a unit weight of 138 lb/ft3. The aggregate
blend is composed of 71% coarse aggregate by weight (Sp. Gr.
2.855), 25% fine aggregate (Sp. Gr. 2.645), and 4% filler (Sp. Gr.
2.550). The compacted specimen contains 6% asphalt binder (Sp. Gr.
1.100) by weight of total mix. Note: Use at least three
decimals for intermediate calculations.
