With rapid growth of population, fast urbanization and more construction of buildings and other structures hasresulted in reduction of good quality available land. There is no choice for People except to use soft and weak soils aroundfor construction activities. Such soil possesses poor shear strength and high swelling & shrinkage. The South Gujaratregion in India have majority of top soil as black cotton soil. The black cotton soil has characteristics of shrinking ondrying and heaving on wetting. This soil being expansive creates several types of damages to pavement structures, and insome cases the pavement may even become unserviceable. A laboratory investigation is carried out to study the effect ofCONSOLID SYSTEM on index and engineering properties of the Black Cotton Soils. The properties of stabilized soil suchas compaction characteristics and California bearing ratio were evaluated and their variations with content of consolid444and Solidry are evaluated and also to evaluate the improvement in properties by the addition of consolid444 and Solidry tobe used in pavement design for economy. A CONSOLID system also reduces thickness of the pavement and save resourcesand construction time. A comparative study of pavement thickness design by IRC METHOD is also done.
