Plasticity inder

A natural soil deposit is to be used for a geotechnical engineering project. Laboratory test results indicate that the soil possesses liquid and plastic limits of LL = 30% and PL = 22%, respectively. In addition, the sieve analysis has produced the following information: • % Passing Sieve No. 4 (4.75 mm) % Passing Sieve No. 200 (75 μm) • Coefficient of Uniformity C₁ 100% 8% 1.590 0.012 Coefficient of Curvature Co (a) Determine the soil's classification in accordance with the Unified Soil Classification System (USCS). (b) To further improve the soil's shear strength performance, the natural soil deposit (possessing an in- situ water content of w = 14%) was compacted in-situ and has achieved a saturation degree of S = 85%. If the specific gravity of soil solids is G, = 2.6, determine the soil's dry and bulk unit weights (ya and y) in its current compacted state.

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

SG is 2.66 and temperature is 18 degrees celcius

Soil mechanic

For a soil specimen, given the following: % passing sieve #4-92 %, sieve #10 -81%, sieve # 40-78%, LL-48%, PL-16%, GI-18.2 classify the soil by AASHTO classification system. GI = (F200-35)[0.2 + 0.005 (LL - 40)] +0.01 (F20015)(PI – 10)

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%.
