Black cotton soil is expansive soil that is prone to large volume changes (swelling and shrinkage) that are directly related to changes in water content. Soil with a high content of expansive minerals can form a deep crack in drier season. By laboratory test and adding stabilizer eventually the durability of soil increases and the occurrence of swelling and shrinkage reduces. Using locally available materials for enhancing soil behaviour is advantageous in terms of Sustainable and economic. It increases bearing capacity of expansive soil so that provide more stability to earthen embankment and slopes. It increases durability. Here we are going to perform Index properties, Compaction, UCS, CBR and Durability tests and analysis of different industrial slags in consideration of cost and strength. We used Bagasse Ash and Lime .This are sustainable alternatives rather than use of common stabilizers which are harmful and Costly. In this project we carry forward project. We used mix proportioning found by them.
