: Black Cotton soil due to its expansive nature possess a serious problem during and after construction of pavement Generally Black cotton soil is removed or replaced with other stronger material when encountered During Construction. Soil stabilization is generally adopted for a given project site, if the existing subgrade is not sufficient to provide the required strength. Also, during contact of Water (Ground water, Rain water) due to swell-shrinkage behavior of expansive soil it causes various problem. On the other hand, due to rapid industrialization throughout the world, large amount of waste material is generated. Out of which Mining waste account a significant portion The Present study was undertaken with the objective of utilizing Mining waste material to poor subgrade and provide a feasible solution which can reduce the environmental impact as well as improve subgrade characteristic. In the experimental study, Black cotton soil was obtained and mixes were prepared with mining waste, lime and coir fiber. Further for attaining better strength Geogrid was inserted at one third height from the top of the CBR mould. The un-soaked and soaked CBR showed a slight improvement in strength. But there was a significant reduction in swell pressure when compared to parent soil.
