$5\mathrm{.}946\mathrm{.}5$ kg $(102\mathrm{.}3$ lb$)$ of fi ne aggregate is mixed with $72\mathrm{.}3$ kg $(159\mathrm{.}1$lb$)$ of coarse aggregate. The fi ne aggregate has a moisture content of$2\mathrm{.}0\%$ and absorption of $3\mathrm{.}4\%,$ whereas the coarse aggregate has amoisture content of $1\mathrm{.}3\%$ and absorption of $3\mathrm{.}8\%.$ What is the amountof water required to increase the moisture contents of both fi ne andcoarse aggregates to reach absorption$?$ Why is it important todetermine the amount of water required to increase the moisturecontent of aggregate to reach absorption$?$
