2. The particle size characteristics of a soil are shown below. Find the percentages of gravel, sand, silt and clay according to the Unified Soil Classification System (USCS) system. Classify this soil using the USCS system. For fines, results from Atterberg limits testing indicated CL-ML. Size (mm) 0.850 Percent finer Size (mm) Percent finer 100.0 0.040 28.0 0.425 100.0 0.020 25.2 0.250 94.1 0.010 21.8 0.150 79.3 0.006 18.9 0.075 34.1 0.002 14.0 Partial Answers 2 SC-SM silty, clayey sand

Given the test results that follow, classify the soil in both the Unified Soil Classification System (USCS) and the AASHTO system.

Define the following properties of soil:           •    1      Liquid Limit           •      2    Plastic Limit                     3     Plasticity Index

Determine the consistency limit.

4. Determine the USCS designation and soil description of a soil sample given the following sieve analysis test results: D10 = 0.2 mm = D30 0.73 mm D60 3.35 mm % passing #4 = 77.5 % passing #200 = 9.5 The fines are silty.

Sr B. ( A Soil Specimen has the following characteristics: % passing No.4 sieve = 85 % passing No.200 sieve = 11 D60 = 2 mm D30=0.35 mm D₁0 = 70 μm D8=2 μm L.L = 36% P.L = 31% 1. Classify the specimen according to the Unified Soil Classification System (USCS). Assign the group name and the group symbol. 2. Determine the soil activity. 3. Determine the soil Liquidity index and consistency index if wc = 26%.
