CIV E 353 Geotechnical Engineering I Assignment 3 Page 1 of 2 Department of Civil Engineering Posted Date: Friday January 22, 2010 Due Date: Monday, February 1, 2010 @ 4pm 1. Soil is excavated from a pit that is to be used for the construction of a landfill liner and berms. The volume of moist soil excavated is 93.45 cm 3 . The moist soil mass is 181.5 g. The soil oven dried mass is 157.0 g. Using phase relationships and a G s of 2.67 determine the soil: 1. Moisture (water) content 2. Bulk density (kg/m 3 ) 3. Dry unit weight (kN/m 3 ) 4. Void ratio 5. Porosity 6. Degree of water saturation 7. Air content 2. A soil has a unit weight of 21.5kN/m 3 , dry soil mass is 140.2 g, G s of 2.65, and water content of 10 percent. Determine the soil dry density, void ratio, degree of saturation, and air content and the saturated soil density and water content. The “chunk density” method is used to determine the unit weight (and other necessary information) of a specimen of irregular shape. The specimen at its in-situ
