MAJOR SOIL CLASSIFICATION SYSTEMS USED IN THE U.S. USDA Textural Classification: Used primarily in agriculture, but not much by civil or geotechnical engineers. AASHTO Classification System: Used quite extensively by civil engineers in selecting soils for usage in roads and highways. THE USDA SOIL TAXONOMY (Soil Survey Staff, 1975; 1999) An introduction to the US Soil Classification (SOIL TAXONOMY) will be given here. The SOIL TAXONOMY is a multi-categorical and hierarchical system of classification.
