To Counter the Heaves on Soil - A Review

Abstract

Heave is the resulting upward movement of an underlying soil layer due to the addition of moisture to an unsaturated expansive soil. Heaves in soil creates more economic loss than any other problems, so there is a great need to overcome this problem. As per the research to overcome the heaves on soil are still a big problem on soil. Black cotton soil causes mainly heaving property with change in water to the soil. Heaves is one of the major problems of soil which occurs everywhere such as roads, bridges, buildings etc. By analysing some paper there are some methods which analyse the heaves and improves the strength and bearing capacity of the soil which tends to reduce the heaving property of soil are one dimensional oedometer, diagnosing heave and to stabilize the heaves by GGBS and lime. The material was discussed in this paper and their effectiveness for reducing the heaves on the black cotton soil. By these methods heaves can reduce effectively and it is economical and do not effect on the environment.
