- 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 soil12. The system divides soils into three major divisions: coarse-grained soils, fine-grained soils, and highly organic soils345. These divisions are further subdivided into 15 basic groups, each with a two-letter symbol (e.g. GW)35. The system is based on both the plasticity characteristics and the particle size of the soil2.Learn more:✕This summary was generated using AI based on multiple online sources.

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.
en.wikipedia.org/wiki/Unified_Soil_Classification_S…A unified classification of soils is the most commonly adopted classification system of soil for engineering purposes. It is, in fact, the universally accepted soil classification system. In this classification system, the soil is classified based on both the plasticity characteristics and the particle size of the soil.dreamcivil.com/unified-soil-classification-system/According to ASTM D2487-17, there are three major soil divisions: coarse-grained soils, fine-grained soils, and highly organic soils. These are subdivided further into 15 basic groups, each with its own group symbol (e.g. GW).blog.ansi.org/2018/03/unified-soil-classification-ast…Soils are divided into four broad categories. These soil categories are coarse-grained soils, fine-grained inorganic soils, organic soils, and peat.www.wsdot.wa.gov/publications/manuals/fulltext/M…Various soils are classified into four major groups:

Unified Soil Classification System - USCS Chart and Applications
- The Unified Soil Classification System is based on the airfield soil classification system developed by Casagrande during World War II (in 1948). With some modifications, it was jointly adopted by several U.S. government agencies in 1952. Additional refinements were made and it is currently standardized as ASTM D 2487-93. It is used in the U.S. and...
