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 most unconsolidated materials, and is represented by a two-letter symbol. Each letter is described below (with the exception of Pt):
If the soil has 5–12% by weight of fines passing a #200 sieve (5% < P#200 < 12%), both grain size distribution and plasticity have a significant effect on the engineering properties of the soil, and dual notation may be used for the group symbol. For example, GW-GM corresponds to "well-graded gravel with silt."
If the soil has more than 15% by weight retained on a #4 sieve (R#4 > 15%), there is a significant amount of gravel, and the suffix "with gravel" may be added to the group name, but the group symbol does not change. For example, SP-SM could refer to "poorly graded SAND with silt" or "poorly graded SAND with silt and gravel."
Classification is a general process related to categorization, the process in which ideas and objects are recognized, differentiated, and understood. A classification system is an approach to accomplishing classification.
Classification may refer specifically to:
Mathematics
Statistical classification, identifying to which of a set of categories a new observation belongs, on the basis of a training set of data
Mathematical classification, a collection of sets which can be unambiguously defined by a property that all its members share
How to Classify Soil using Unified Soil Classification System (USCS) | Examples of Different Soils
This video explains how to classify four different soils using the Unified Soil Classification System (USCS). There are four soils to be classified in this video. Soil 1 0:01:41 Soil 2 0:03:50 Soil 3 0:05:55 Soil 4: 0:08:33. First two soils (Soil 1 and Soil 2) are coarse-grained soils and also non-plastic. We will classify them based on their gradation, which means that we will need to determine the coefficient of curvature and coefficient of uniformity. Soil 3 and Soil 4 are plastic soils, we are required to classify them based on their plasticity, using the plasticity chart https://youtu.be/sGt8ZIldsVA

CEEN 341 - Lecture 5 - Soil Classification
This lecture introduces you to the idea of soil classification and why geotechnical engineers do it. Steps are provided to use the AASHTO classification system and the Unified Soil Classification System (USCS). Examples are performed.
Critical Questions to Consider:
1) Why do geotechnical engineers perform soil classification?
2) What are the differences between the AASHTO and the USCS systems?
3) Why don't we use the USDA system for engineering applications any longer?

How to Use the Plasticity Chart | Everybody MUST Know to Classify Soil
This video explains how to use the plasticity chart to classify two plastic soils. Soil 1 0:01:24 Soil 2 0:02:10. The A-line defines the boundary between clay (above the line) and silt (below the line). In some cases when you can't visually deicide of the point is above/below or right on the A-line, you can use this relationship that PI must be greater than 0.73x(LL-20) for soil to be classified as clay.

How to Classify Soil using Unified Soil Classification System https://youtu.be/VQNxhNTslX0
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 most unconsolidated materials, and is represented by a two-letter symbol. Each letter is described below (with the exception of Pt):
If the soil has 5–12% by weight of fines passing a #200 sieve (5% < P#200 < 12%), both grain size distribution and plasticity have a significant effect on the engineering properties of the soil, and dual notation may be used for the group symbol. For example, GW-GM corresponds to "well-graded gravel with silt."
If the soil has more than 15% by weight retained on a #4 sieve (R#4 > 15%), there is a significant amount of gravel, and the suffix "with gravel" may be added to the group name, but the group symbol does not change. For example, SP-SM could refer to "poorly graded SAND with silt" or "poorly graded SAND with silt and gravel."
Sand grains, according to the standards body ASTM International’s Unified SoilClassificationSystem, are soil particles having a diameter of 0.003 inches (0.075 mm) to 0.187 inches (4.75 mm) ... And soil with particles larger than sand size is gravel.
