In an ongoing land development project, a Contractor requested for a concrete pouring request. After conducting a field density test in Road Lot 1 and 2, the results of Sand Cone Method (ysand = 16.353 kN/m³) are as follows: Total Weight of Retained Mass of Sand Moisture Content (%) Location Weight of Soil Sample (kg) 1.39 1.30 Sand (kg) 7.40 7.40 (kg) Road Lot 1 Road Lot 2 6.2 20% 6.3 19% Properties of Soil base on Soil Investigation Result: Specific gravity of Soil Particles – 2.75 Weight of Soil Sammple - 1.6309 kg Volume of Soil Sample – 0.0009 cu.m.

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.
Boreholes reveal that a thin layer of alluvial silt exists at a depth of 50 ft below the surface of the ground. The soil above this level has an average dry unit weight of 96 lb/ft3 and an average water content of 30%. The water table is approximately at the surface. Tests on undisturbed samples give the following data: cu = 1008 lb/ft2, undrained friction angle = 13°, cd = 861 lb/ft2, drained friction angle = 23°. Estimate the shearing resistance in psf of the silt on a horizontal plane when the shear stress builds up rapidly. with fbd a.2185 b.2449 c.861 d.3120
