A contractor excavates 10,000 m3 soil at moist unit weight of 17.5 kN/m3 and moisture content of 10% from a borrow pit and transports it to a project site. The project has an area of 20,000 m2 to be filled with this compacted soil. If the required dry unit weight and moisture content of the compacted soil are 18.3 kN/m3 and 12.5% (assume there is no soil loss during transportation and compaction), what is the thickness of the compacted soil and how much water needs to be added? If there are 2% dry soil loss and 3% moisture loss, what is the thickness of the compacted soil and how much water neeeds to be added to maintain the compaction at the required moisture content?

Question
A contractor excavates 10,000 m3 soil at moist unit
weight of 17.5 kN/m3 and moisture content of 10%
from a borrow pit and transports it to a project site.
The project has an area of 20,000 m2 to be filled with
this compacted soil. If the required dry unit weight
and moisture content of the compacted soil are 18.3
kN/m3 and 12.5% (assume there is no soil loss during
transportation and compaction), what is the thickness
of the compacted soil and how much water needs to be
added?
If there are 2% dry soil loss and 3% moisture loss, what is the thickness of the compacted soil and how much water neeeds to be added to maintain the compaction at the required moisture content?
