Gradation parameters of soil (a) are: D10 = 0.08 mm, D30 = 0.22 mm, and D60 = 0.41 mm. and for soil (b), gradation parameters are: D10 = 0.24mm, D30 = 0.82, and D60 = 1.81mm. Calculate the coefficient of uniformity and the coefficient of curvature. Compare the soils based on their gradation parameters and discuss the expected engineering behavior of each soil.

The embankment for a highway 5097 ft long, 104 ft wide and 6 ft 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 6.748% and its porosity is 0.422. The specification requires the embankment be compacted to a dry unit weight of 122.874 lb/ft3. The specific gravity is 2.588. Determine the following: a. Total weight of the soil solids, kips. b. Total volume of the soil required from the borrow pit, ft3. c. Weight of water to be added per foot length of the embankment to reach 10% moisture content, lb.Round off answers to three decimal places.
