1. The maximum density corresponds to (maximum/minimum). 2. An increase in the degree of saturation of a soil (increases/decreases) permeability. 3. Shortcoming of direct shear test is that it fails the soil on a designated plane which may not be the weakest one. (a) True (b) False 4. Compaction means the decrease of air voids. (a) True (b) False 5. To determine the grain size distribution of fine-grained soil (smaller than 0.075 mm), Hydrometer test should be conducted. (a) True (b) False 6. In triaxial test, cell pressure is applied to simulate the actual field condition of the sample in the laboratory. (a) (b) False 7. Sand cone method can be used to determine the in-situ density (field density) of soil. (a) True (b) False True 8. What is the particle size (diameter) distribution of clay soil? (a) Smaller than 0.002 mm (c) 0.005 mm to 2.0 mm (b) (d) 9. Specific gravity of clay soil ranges from (a) 2.70-2.80 (b) 2.20-2.50 10. Typically, permeability of clay soil is: void ratio. 0.002 mm to 0.05 mm greater than 2.0 mm (c) 2.60 -2.70 (d) 2.85-2.95 (a) Very low (b) very high (c) high to medium (d) Low to medium
