Answer:
total weight of the aggregate = 3594878.28 lbs
Explanation:
given data
density = 121.8 lb/ft³
area = 1000 ft x 60 ft x 6 in = 1000 ft x 60 ft x 0.5 ft
moisture = 3.5 %
compaction = 95%
solution
we get here first volume of the space that is filled with the aggregate that is
volume = 1000 ft x 60 ft x 0.5 ft = 30,000 cu ft
now we get fill space with aggregate that compact to 95% of dry density.
so we fill space with aggregate of density that is = 95% of 121.8
= 115.71 lb/ cu ft
so now dry weight of aggregate is
dry weight of aggregate = 30,000 × 115.71 = 3471300 lb
when we assume that moisture percentage is by weight
then weight of the moisture in aggregate will be
weight of the moisture in aggregate = 3.56 % of 3471300 lb
weight of the moisture in aggregate = 123578.28 lbs
and
we get total weight of the aggregate to fill space that is
total weight of the aggregate = 3471300 lb +123578.28 lb
total weight of the aggregate = 3594878.28 lbs
