Question

Classify the following soils using the AASHTO classification system. Give group indexes as well.

### Sieve Analysis and Soil Properties #### Table: Sieve Analysis, % Finer | Soil | No. 10 (%) | No. 40 (%) | No. 200 (%) | Liquid Limit | Plasticity Index | |------|------------|------------|-------------|--------------|-----------------| | A | 48 | 28 | 6 | -- | NP | | B | 87 | 62 | 30 | 32 | 8 | | C | 90 | 76 | 34 | 37 | 12 | | D | 100 | 78 | 8 | -- | NP | | E | 92 | 74 | 32 | 44 | 9 | #### Explanation of Columns: - **No. 10, No. 40, No. 200**: These columns represent the percentage of soil particles that pass through sieves of different mesh sizes. No. 10, No. 40, and No. 200 indicate finer particle content. - **Liquid Limit**: The water content at which soil changes from a plastic to a liquid state. A dash (--) indicates data not available. - **Plasticity Index**: This value is the difference between the liquid limit and the plastic limit, indicating the range of moisture contents over which the soil behaves plastically. "NP" stands for "Non-Plastic", indicating the soil does not exhibit plasticity. #### Analysis Notes: - Soil sample A and D have a significant percentage of small particles but are non-plastic. - Soil samples B, C, and E have varying degrees of plasticity, with E having the highest liquid limit. - Understanding these properties is crucial for determining the suitability of soil for construction and engineering projects.
