If soils cumulatively retained on sieve #4 is 68%, then the percentage of soil classified as sand, silt, and clay

A cone penetration test has been conducted, and has measured a cone resistance of 85 kg/cm² at a depth of 10 m. The vertical effective stress at this depth is 150 kPa, and the overconsoliation ratio is 2. The soils at this depth are quartz sands. Compute the relative density, and classify the soil using Table 3.3.

Use the USDA soil classification triangle to determine the textural soil class designations with the distributions of particle sizes shown in the table (unit is mm).

Classify the following soils using the U.S. department of Agriculture textural classification chart. PARTICLE - SIZE DISTRIBUTION (%) SOIL SAND SILT CLAY A 30 58 12 B 40 25 35 30 25 45 D 45 50 45 45 10
