3. An embankment with a total volume of 30,000m3 is to be constructed as part of a highway project. The soil to be used in the embankment will come from a borrow pit where the average moist unit weight and water content of the soil is 17.6kN/m3 and 13% respectively. Assuming that the soil will be compacted to a dry unit weight of 18.2kN/m3 at a moisture content of 16%. a. Compute the weight of dry soil required. b. Compute the volume of borrow required. c. Compute the total quantity of water in cubic meters that must be added to the fill during compaction to bring about a desired final moisture content of 16%.
