Word ‘Soil’ has been derived from Latin word ‘Solum’ meaning earthy material required for the growth of plants. Soil can be defined as a combination of organic as well as weathered rock ingredients present in the topmost part of earth soil crust. Soil Science or Penology (pedos means earth) is the branch of science that deals with the study and classification of soils.

In order to decide different compound and physical attributes of soil and their separate representation a few Classification frameworks are utilized. Soils are gathered by their request of execution under given arrangement of physical conditions.

Numeral grouping frameworks have been produced depending upon the planned reason for the framework. Soil characterization has turned out to be an extremely helpful instrument to the soil engineers. It gives general rules in an experimental way to make utilization of the field experience of others.

Soil might be comprehensively classified as described below.

  1. Classification in assessment of grain size
  2. Textural Classification
  3. AASHTO Classification framework
  4. Unified soil Classification system

Grain Size Classification System for Soils

Grain size frameworks depended on soil grain measurement. In this framework the terms clay, slit, sand and gravel are used to demonstrate just the particle size and the nature of soil type is not observed.

Textural Classification of Soil

The arrangement of soil solely in view of particle measure and the rate of its dispersion is known as textural classification framework. This framework particularly names the soil considering the percentage of sand, slit and clay. The triangular charts are utilized to arrange soil by this framework.

AASHTO classification of Soil

AASHTO classification system, also called as PRA classification system. It was initially created in 1920 by the U.S. Agency of Public Roads for the grouping of soil for expressway subgrade utilize. This framework is created in light of molecule size and plasticity attributes of soil mass. After some updates, this framework was received by the AASHTO in 1945. In this framework, the soils are separated into seven noteworthy groups. Few of the significant groups are additionally separated into subgroups.

Unified Soil Classification System

Unified Soil classification system was initially created by Casagrande (1948) and was known as air field classification system. It was accepted with some change by the U.S. Authority of Reclamation and the U.S. Corps of Engineers. This framework depends on both grain size and the versatility qualities of soil. A similar framework with minor alteration was adopted by ISI for general building design (IS 1498 – 1970). IS framework separates soil into three noteworthy groups, coarse grained, fine grained and organic soils and different soil materials?

Coarse grained soils are those with over half of the material bigger than 0.075mm size. Coarse grained soils are additionally characterized into rock (G) and sands (S). The rock and sands are additionally partitioned into four classifications as per degree, sediment or soils substance. Fine grained soils are those for which over half of soil is better than 0.075 mm sifter estimates. They are separated into three sub-divisions as silt or residue (M), clay (c), and organic salts and soil (O). in view of their plasticity nature they are included with L, M and H image to show low plastic, medium plastic and high plastic individually.
