Question
**Classify the following soils according to the AASHTO Soil Classification with Group Index (GI):** The table provides data for two soil samples, A and B, with the percentage of each sample passing through various U.S. standard sieves, along with their Liquid Limit (LL) and Plastic Limit (PL). | Soil | Percent passing U.S. sieve | LL | PL | |------|----------------------------|----|----| | | No. 4 | No. 10 | No. 20 | No. 40 | No. 60 | No. 100 | No. 200 | | | | A | 95 | 86 | 65 | 52 | 46 | 38 | 25 | 38 | 22 | | B | 100 | 98 | 95 | 88 | 82 | 75 | 65 | 65 | 58 | - **Soil A:** - Sieves: Higher percentage retained in finer sieves, indicating it has more fine particles. - Liquid Limit (LL): 38 - Plastic Limit (PL): 22 - **Soil B:** - Sieves: Higher percentage passing through all sieves, suggesting it is finer overall. - Liquid Limit (LL): 65 - Plastic Limit (PL): 58 This classification process requires you to determine the textural class of each soil type, using both the percentage passing through sieves and the limits for plasticity.
