Abstract

Due to growth of population and reduction of available land, increasing construction of highway/runway pavement and other civil engineering structure need to carry out on weak and soft soil. Black cotton soils are inorganic clays of medium to high compressibity and form a major soil group in India. They are characterized by high shrinkage and swelling properties. Owing to such high swelling and shrinkage characteristics, the Black cotton soils (BC) soil has been a challenge to the highway engineers. The Black cotton soil is very hard when dry, but loses its strength completely when in wet condition. In this work, BC Soil was tested using two different stabilizing agents - Terrasil & Lime. Investigation includes evaluation of grain size distribution, Atterberg’s Limit, Maximum Dry Density, Optimum moisture content, CBR value and UCS value of Black cotton soil Specimens with and without stabilizers for a curing period.
