A plastic limit test has been performed on a soil. Threads of the soil that broke at a diameter of 1/8 in. were collected for a moisture content test, which yield the following results: Mass of soil + can before placing in oven 41.30 g Mass of soil + can after removal from oven 37.40 g Mass of can 22.20 g Compute the plastic limit of the soil. Express it in percentage (input the numerical value only without including the % sign).

05: The Figure below represents the data that was obtained from a liquid-limit test on a soil. 50 percent of its particles is passing sieve #200. Two determinations for the plastic limit gave water contents of 20.3 % and 20.8 %. Determine 1- Liquid Limit (LL). 2- Plasticity index. 3- Liquidity index if the water content is 27.4% 4- Void ratio at the liquid limit, if G, 2.7 5- Classify the soil based on AASHTO system. 30 10 20 40 60 80 100 Penetration, d (mm) Moisture content, w ()

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.

SITUATION 3: A 100 cc proctor mold was used to collect a wet soil sample. Its weight was found to be 200 gms. Its oven dried weight was recorded as 189 grams. G = 2.7 7. The moisture content is most likely: a. 0.058201 c. 0.069841 8. Its void ratio is: a. 0.771429 c. 0.514286 b. 0.064021 d. 0.046561 b. 0.471429 d. 0.428571

PROBLEM No. 5 A test of density of soil in place was performed by digging a small hole in the soil, weighing the extracted soil, and measuring the volume of the hole. The soil (moist) weighed 895 g; the volume of the hole was 426 cm³. After drying, the sample weighed 779 g. Of the dried soil, 400 g was poured into a subsequently determined to be 276 cm³. That same 400 g was then vibrated and tamped to volume of 212 cm³. If the specific density is 2.71, determine the following: vessel in a very loose state. Its volume was Moist unit weight in g/cm³. Minimum dry unit weight in g/cm³. Maximum dry unit weight in g/cm³. а. b. С. d. Void ratio in natural state. е. Void ratio in loosest state. f. Void ratio in densest state. g.
