What are tests are used to classify soil?

Soil field tests are visual-manual methods for field examination of soil. The field tests provide the means for a consistent description of soil including developing information for a preliminary identification of soil type under the Unified Soil Classification System (USCS) during field mapping and site investigation (Johnson and DeGraff 1988; USBR 1998).

What does soil classification stand for?

Soil classification is the grouping of soils with similar engineering properties into a category by using the results of laboratory-based index tests, e.g., group name and symbol (ASTM D 2487, AASHTO M 145). It is important to distinguish between a visual description of a soil and its classification in order to minimize
