Question

what are the USCS group name for each of the four gradations

**Grain Size Distribution Analysis** **Standards:** ASTM D422 / ASTM C136 This chart represents the grain size distribution using a semi-logarithmic plot, detailing the relationship between grain size and the percentage of fineness by weight. **Graph Explanation:** - **Axes:** - **Horizontal Axis:** Represents grain size in millimeters (bottom) and U.S. sieve sizes (top). The scale is logarithmic. - **Vertical Axis:** Represents the percentage of material finer than each sieve size by weight, ranging from 0% to 100%. - **Curves:** Several curves plotted across the graph indicate different samples with specific markers for each sample type: - **B-02:** Star markers - **B-04:** Circle markers - **B-08:** Triangle markers - **B-09:** Square markers **Material Classification (Bottom Scale):** - **Cobbles** - **Gravel:** Coarse and fine - **Sand:** Coarse, medium, fine - **Silt or Clay** **Boring Data Table:** | Boring ID | Depth (ft) | USCS Classification | WC (%) | LL | PL | PI | Cc | Cu | |-----------|------------|----------------------|--------|----|----|----|----|----| | B-02 | 8 - 10 | - | 53 | 24 | 29 | | | | B-04 | 9 - 11 | NP | NP | 1.05 | NP | | 95.52 | | B-08 | 6 - 8 | 27 | 16 | 11 | 3.08 | | 28.34 | | B-09 | 8 - 10 | NP | NP | 2.72 | NP | | 9.97 | - **Legend:** - **WC (%)**: Water Content - **LL**: Liquid Limit - **PL**: Plastic Limit - **PI**: Plasticity Index - **Cc**: Coefficient of Curvature - **Cu**: Coefficient of Uniformity The graph is essential for interpreting soil characteristics relevant for engineering and construction applications.
