A coarse aggregate sample was dried in an oven for 1.5 hours before it was immersed in water for 24 hours then rolled in an absorbent cloth to dry the surfaces of the aggregate. The weight in this condition is found to be 3002 g. It was transferred to a density basket to determine its weight in water which was recorded to be 1910 g. it was then poured in a drying pan and dried in the oven. The weight after drying was 2965 g.

46.5 kg (102.3 lb) of fine aggregate is mixed with 72.3 kg (159.1 lb) of coarse aggregate. The fine aggregate has a moisture content of 2.0% and absorption of 3.4%, whereas the coarse aggregate has a moisture content of 1.3% and absorption of 3.8%. What is the amount of water required to increase the moisture contents of both fine and coarse aggregates to reach absorption? Why is it important to determine the amount of water required to increase the moisture content of aggregate to reach absorption? Use one system of units only as specified by the instructor.
