Abstract: Black Cotton (BC) soil is a clayey and highly plastic in nature. In dry state it is so hard that the clods cannot be easily pulverized and this poses serious problems as regards to subsequent performance of the road. The roads laid on BC soil bases develop undulations at the road surface due to loss of strength of the sub grade through softening during monsoon. These soils need to be stabilized before constructing the roads in order to have efficient and long lasting roads. Efforts are therefore required to strengthen the sub grade soil by mechanical stabilization of BC soil to improve its performance.The objective of this study is to evaluate the strength characteristics of black cotton soil stabilized with waste pulverized glass in varying proportions. The glass used in the present study is pulverized glass used in window glass panes. Two different size of glass were used in the study, passing through 20 mm sieve and retained on 4.75 mm, and passing through 4.75 mm sieve and retained on 75 micron sieve. Further the glass was mixed with the BC soil in proportions of 10% and 20% of the weight of soil. Laboratory investigations were performed on the above combinations and Atterberg’s limit, Compaction test and California Bearing Ratio (CBR) test were performed for evaluation of strength characteristics of BC soil stabilized with waste glass.
