To classify a soil, tests are performed according to the American Society for Testing and Materials standards, and the results of these tests are used in a classification system recommended by the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE). The tests are the sieve analysis, the hydrometer analysis, and the Atterberg limits. The classification system is called the Unified Soil Classification System (USCS). The USCS is the system used internationally to classify soils. Most commonly, it employs a two‐letter symbol. The American Association of State Highway and Transportation Officials (AASHTO) has developed another soil classification system for highway construction purposes starting in 1929. This classification is quite different from the ISSMGE USCS starting with the AASHTO classification designation being A‐1 to A‐7 instead of the dual letter symbols of USCS.
