Soil stabilization is the process of improving the engineering properties of the soil and thus making it more stable. It is required when soil available for construction is not suitable for the intended purpose. Unstable clay soils can create significant problems for pavement or structures, therefore soil stabilization techniques are necessary to ensure the good stability of clay soil so that it can successfully sustain the load. Black cotton soil which is one of the major soil deposits in India becomes highly problematic because of its property of higher degree of swelling and shrinkage. This study focuses on the impacts of conventional ground improvement techniques and alternative of these such as by adding brick powder which contains higher proportions of silica and is found near brick kilns in rural areas the objective of the study is to investigate the use of lime-stabilized black cotton soil and brick powder mixture as subbase material in flexible pavements. Lots of parameters have been selected for comparison including index properties and consolidation characteristics. After the results were obtained they were found to be promising and ecofriendly as subbase material in flexible pavements.
