Abstract:

Expansive soils are highly problematic because of their nature of soils to undergo large volumetric change due to variations in the moisture content. These soils cover approximately 20% of total land area in India. Changes in volume resulting from variations in moisture in expansive soils and expansive soil subgrades cause damage to structures, highway pavements and other civil engineering infrastructure. This paper deals with the properties of black cotton soils or “regur” soils found in India which are expansive in nature. The paper presents a summary of technologies used to identify, test and treat expansive soils. The paper also discusses geological, mineralogical and physical properties of expansive soils along with categorization of technologies and testing methods with respect to applicability in Highway Engineering. The experimental results of different reports and research papers have been examined and summed up in this paper to suggest multiple remedial techniques in order to overcome the problems posed by expansive soils and to develop economic methods in road and rail construction.
