Situation 5: 12. 13. 14. 15. An embankment for a highway 30 m wide and 1.3 m in compacted thickness is to be constructed from a sandy soil trucked from a borrow pit. The water content of the sandy soil in the borrow pit is 17% and its void ratio is 0.75. The specification requires the embankment to be compacted to a dry unit weight of 19 kN/m³. The length of embankment is 3 km. Use G = 2.7. Compute the volume of borrow material required. Solve the total cost of fill if the earth fill from borrow site costs P200/m³ Calculate the volume of borrow material required if the specification requires a void ratio of 0.20.
