the soil in a borrow pit has a water content of 11.7% and a dry unit weight of 16.65 kN/m^3. If 2,070 m^3 of this soil is excavated and compacted in an embankment at a porosity of 0.33, compute the compacted volume of the embankment that can be constructed with this soil. The specific gravity of solids is 2.7
Homework Answers

of soil solids will remains same, only due to change in void ratio
of two state natural volume of soil will get changed
