Performance of Lateritic Soil Mixed with Black Cotton Soil

Abstract

Due to increase of the population of the world requires various civil engineering structures to fulfill the needs of human beings. Soil is ommon material used in backfills, earthen dam, embankment of road construction and various civil engineering structures. In India soil covers one third area and many other types of soils are present all over the remaining part of the country. In the above mentioned structures, we mainly use soil. The soil is having its own physical properties as well as engineering properties. There are mainly three types of soil namely Black cotton soil, lateritic soil and sand. In north Karnataka black cotton soil is having high swelling and low permeability properties, lateritic soil having low swelling and medium permeability properties. The design of mixed soil is required for appropriate use of soil mix for civil engineering works which may be Black cotton and Lateritic soil to get desirable compaction, permeability and free swelling potential. The results revealed that mixed soil behaviors have direct co relation with higher value of MDD, low permeability and low free swelling potential.
