Laboratory specific gravity and absorption tests are run on two coarse aggre- gate sizes, which have to be blended. The results are as follows: Aggregate A: Bulk specific gravity = 2.491; absorption = 0.8% Aggregate B: Bulk specific gravity = 2.773; absorption = 4.6% a. What is the specific gravity of a mixture of 60% aggregate A and 40% aggregate B by weight? b. What is the absorption of the mixture?
