Stabilization of petroleum contaminated red soil by using lime

The admixture lime is used for stabilization. In the current study is to explore the features of petroleum-contaminated soil stabilized with admixture at various percentages, including maximum dry density and ideal moisture content. The properties of petroleum contaminated soil were: Free swell index (FSI)=52%, Specific gravity (SG)=2.4, Liquid Limit (LL) and Plastic Limit (PL)=86.10 % and 40.10% respectively, Plasticity Index (PI)=46%, Maximum Dry Density (MDD) and Optimum Moisture Content (OMC) =1.22g/cc and 34%. There was a decrement in liquid limit up to 7.42% upon the addition of lime with 30% dosage. Optimum dosage lime is found to be 20% and values of MDD and OMC of petroleum contaminated soil were 1.38gm/cc and 28% respectively. A combinational parametric research has been carried out by petroleum contaminated soil and lime. Optimum 20% lime was mixed with petroleum contaminated soil in the range 10% to 40%. Lime enhanced engineering properties as compared to parent soil. It was found that petroleum contaminated soil stabilized with 20% lime showed improvement in strength i.e.,0.5Kg/cm^2.
