stabilisation of black cotton soil using bioenzymes for pavement construction ppt

Abstract

In developing countries like India the most important requirement of any project after performance criteria is its economical feasibility and serviceability criteria. The conventional methods are time consuming and are not economically feasible. Hence there is a need to discover the other possible ways to satisfy the performance as well as economical criteria. In this paper, popularly available bio-enzymes and their effect on engineering properties of s ....etc

Black cotton soils and oher expansive soils have typical characteristics of shrinkage and swelling due to moisture movement through them. During rainy season, moisture penetrates into these soils, due to which they swell. Most of the fine grained clays, including black cotton soils have their grains which are more or less in the form of platelets or sheets (just like leafs of a book), and their grains are not round. When moisture enter betwecn the platelets under some hydrostatic pressure, the particles separare out, resulting in increase in th ....etc

Black cotton soils are highly clayey soils
grayish to blackish in color. They contain montmorillonite
clay mineral which has high expansive characteristics. Black
Cotton soils have low shrinkage limit and high optimum
moisture content. It is highly sensitive to moisture changes.
While laying roads or constructing foundations, the sub grade
and its undesirable characteristics need to be modified using a
suitable stabilization technique. Stabilization involves the
methods used for modifying the properties of a soil to improve
its enginee ....etc
