The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to …

The Unified Soil Classification System uses a two-letter system to name different soil types. The chart below also includes a plasticity chart that is used to determine the classification of fine-grained soils.

Determine percentages of sand and gravel from grain-size curve. Depending on percentage of fines (fraction smaller than No. 200 sieve size), coarse-grained soils are classified as follows: Less than 5 …

To ensure proper application of the criteria for classifying soils, the latest version of the “Keys to Soil Taxonomy” is needed. In addition, this guide omits all information needed to classify soils to the …
