PART B x 16 80 Marks)
11. Sandy soil in a borrow pit has unit weight of solids as 25.8 kN/m3, water content equal to 11% and bulk unit weight equal to 16.4 kN/m3. How many cubic meter of compacted fill could be constructed of 3500 m3 of sand excavated from borrow pit, if required value of porosity in the compacted fill is 30%. Also calculate the change in degree of saturation.

14. Briefly explain about direct shear test. State the advantages and limitations of this test.
Or
Explain the procedure involved in the tri-axial compression test with neat sketch.
15. Explain any one method in detail, by which the stability of a finite slope can be investigated.
Or
