rdso.indianrailways.gov.inThe Geotechnical Engineers/Agencies had evolved many soil classification systems, over the world. The soil classification system developed by Casegrande was subsequently modified and named as 'Unified Classification’ system. In 1959, Bureau of Indian Standards adopted, the Unified classification system as a standard, which was revised in 1970.

pdhonline.coma. Gravel and Sand. Gravel and sand have essentially the same basic engineering properties, differing mainly in degree. The division of gravel and sand sizes by the 4.75-mm sieve is arbitrary and does not correspond to an abrupt change in properties. When devoid of fines, coarse-grained soils are pervious, easy to compact, and have little affect
