Geotechnical enhancement of clayey soil treated with Phosphogypsum,Flyash &Lime

1.)    Plasticity behavior (WL,Ws,Wp,Ip,) is improved with res- pect to virgin soil. 2.)  MDD increases After optimum compaction, which stabilizes the soil to use it for Engg. Purposes like pavement subgrade construction, foundation work etc. 3.)   CBR value increases as to the desired range so that upto this level the soil is fit to use for the construction purposes. 4.)    A step is taken towards the sustainable development as the industry waste PG&FA can be used as construction material to stabilizes the soil for achieving its desired Engg.
