10. Use the USCS soil classification system to classify the soil shown in the following particle size distribution curve. \( (/ 3) \) USCS Classification: Table 2 - Unified Soil Classification System Unified Soil Classification System (ASTM designation D-2487) Nore: The "U" line represents approximate upper limits of \( w_{L} \) and \( t_{P} \) for natural soils. The "A" line separates the silt (M) and clay \( (C) \) soils. Fine-grained soils with plasticity values in the hatched area are classified as CL-ML. Fibrous organic matter: will char, burn, or glow passing \( 75 \mu \mathrm{m} \), have a dual symbol. W or P for the lype of fines, e.g.,SP.SC. - Note: To identify OL and OH soils, test for liquid limit as found and for liquid limit of ovendried samples. If oven-dried values are less than \( 75 \% \) of the original values, woils are OL. or \( \mathrm{OH} \).
