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.

Soil classification and characteristics

Soil classification is a method of categorizing soil based on its properties, types, and uses. The motive of soil classification is to arrange various types of soils and divide them into groups for various engineering and agricultural purposes. Soil classification is carried out by various agencies as per their purposes. From an engineering perspective, soil classification is done to find out the suitability of soil for various construction purposes like the construction of dams, foundations, highways, infrastructures, and so on. For engineering purposes, the soil is classified by the following systems:

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.
