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.

Considering that approximately equal amounts of coarse and intermediate aggregate will be used in the mix, what is the percentage of fine aggregate that will give a resulting minus No. 200 in the mixture in the middle of the range,about 4%?
