Given the test results that follow, classify the soil in both the Unified Soil Classification System (USCS) and the AASHTO system.

 

### Soil Sieve Analysis and Classification **Particle Size Distribution** This table presents the results of a sieve analysis based on U.S. Standard Sieves. It outlines the percentage of sample soil material passing through each sieve size: - **Sieve No. 4:** 48% passing - **Sieve No. 10:** 42% passing - **Sieve No. 40:** 34% passing - **Sieve No. 100:** 25% passing - **Sieve No. 200:** 10% passing **Soil Classification Parameters** - **Coefficient of Uniformity (Cu):** 4.2 - **Coefficient of Curvature (Cc):** 1.5 **Atterberg Limits** These values assess the critical water contents of fine-grained soils: - **Liquid Limit (LL):** 42 - **Plastic Limit (PL):** 34 **Soil Classification** - **USCS Group Symbol:** The Unified Soil Classification System (USCS) symbol is not provided. - **AASHTO Group Classification:** The American Association of State Highway and Transportation Officials (AASHTO) classification is not provided. This data is essential for understanding the soil's granular composition and behavior under varying moisture conditions, which is crucial for engineering and construction applications.
