Given four different types of aggregates to be used to produce a blended aggregate for use in the manufacture of asphaltic concrete, determine the bulk specific gravity of the aggregate mix.
What will be an ideal response?
The bulk specific gravity of the proposed mix is simply a weighted average of the
bulk specific gravities of the aggregates in the blend.
Gsb = (0.38)(2.62) + (0.42)(2.58) + (0.12)(2.63) + (0.08)(2.54)
G = 2.60
