In civil engineering, the description and classification of soil for engineering purposes is the basis for communication among engineers all over the world, the aim being to ensure better understanding and comparison of in-situ and laboratory test results. The engineering classification of soil enables engineers to generally estimate the type of soil and the range of its mechanical properties. By classification according to principles determined in advance, different types of soil can be classified into groups with similar mechanical properties and behaviour under load. The best known and the most widespread engineering classification of soil is the USCS (Unified Soil Classification System), which is presented in ASTM D 2487-11
