Another asphaltic concrete mixture consists of 42% coarse aggregates, 51% fine aggregates, and 7% mineral fillers. The respective bulk specific gravities of these materials are 2.600, 2.710, and 2.690. The asphalt cement content of the total weight of the mix of a sample is 5.5%. The bulk specific gravity of the sample was calculated as 2.467, and the maximum bulk specific gravity of the mix was estimated using ASTM D2041 as 2.562. Determine the value of the sample's air voids,...
