11. Use the USCS soil classification system to classify a fine-grained soil based on the Atterberg Limits information below ( /3) Table 2 - Unified Soil Classification System Unified Soil Classification System (ASTM designation D-2487) Note: The "U" line represents approximate upper limits of $$w_L$$ and $$I_p$$ for natural Organic clays of medium _ soils. The "A" line separates the silt $$(\mathrm{M})$$ and clay $$(\mathrm{C})$$ soils. Fine-grained soils to high plasticity with plasticity values in the hatched area are classified as CL-ML. Peat, muck, and other Fibrous organic matter: will char. highly organic soils burn, or glow * Note: Coarse-grained soils with 5 to $$12\%$$ passing $$75?\mathrm{m}$$, have a dual symbol, W or $$\mathrm{P}$$ for the grain size distribution, and $$\mathrm{M}$$ or $$C$$ for the type of fines, e.g., SP-SC. **Note: To identify OL and OH soils, test for liguid limit as found and for liquid limit of ovendried samples. If oven-dried values are less than $$75\%$$ of the original values, soils are $$\mathrm{OL}$$ or OH.
