You were tasked to draw the Soil-Water Characteristic Curve (SWCC) of four types of soil: sand, clay, silt and glacial till. Reference the suction value at 10 kPa, which type of soil will have the highest degree of saturation?

Determine the following: a.) The plasticity index of soil A. b.) The liquidity index of soil B if its natural moisture content is 48%. c.) The natural moisture content of soil A if its liquidity index is 2.1.

please answer all

Soil Mechanics. Please Solve ASAP.

3. Determine the classification of soil being used as a highway subgrade using AASHTO Classification System with the following data below. Sieve Analysis: Percent Finer No. 10 = 88% No. 40 = 75% No. 200 = 34% Plasticity for the minus No. 40 Fraction Liquid Limit = 39% Plasticity Index = 12%

Please show all calculations. I need help understanding my homework, Thank you!
