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

2. [10] A segment of interstate highway requires the construction of an embankment of 500,000 yds. The embankment fills to be compacted to a minimum of 90% of Modified Proctor maximum dry density. A source of suitable borrow has been located for construction of the embankment. Tests showed that the required dry density can be achieved with the existing moisture content of the borrow pit material. The following data is provided: Dry unit weight of soil in the borrow pit...
