Laboratory specific gravity and absorption tests are run on two coarse aggregate sizes, which have to be blended. The results are as follows: Aggregate A: Bulk specific gravity = 2.814; Absorption = 0.4% Aggregate B: Bulk specific gravity = 2.441; Absorption = 5.2% a. What is the specific gravity of a mixture of 50% aggregate A and 50% aggregate B by weight? b. What is the absorption of the mixture?
