Soil is very significant in civil engineering construction. Soil having poor engineering properties may create many problems. To make the soil suitable for the desired level of construction, it is necessary to augment the engineering characteristics of soil. There are various methods of improving the engineering properties of soil. The soil stabilization technique is one of the most effective tools used now days for enhancing the engineering properties of soil. But the soil stabilization is becoming costly day by day due to the rise in cost of stabilizing agent like cement, lime etc. On the other hand large quantity of waste material produced from the different industries like fly-ash, rice husk ash, plastic waste, paper mill slag etc. create negative impact on the environment causing environmental pollution and hence safe disposal of these waste material is required. Utilized these waste material as stabilizing agent for improving engineering properties of poor soil is best solution and also using these waste material as a stabilizing agent not only solve the dumping issue but as well as minimize the expenditure of stabilization. In this research work, an extensive laboratory work have been done to explore the use of local available RHA as agricultural waste and waste fibres of the polypropylene for the improvement of the various properties of the Clayey (CI) type of soil obtained from proposed site of D.A.V. public school (junior wing) behind cloth market Ambala City, Haryana (India).The objective of this work to explore the effect of waste fiber of polypropylene in different length i.e. 10mm, 20mm, 30mm and different percentage i.e. 0.20%, 0.30%,0.40% as reinforcement mixed with optimum amount of RHA stabilized soil. The effect on engineering characteristics of clayey soil as well as RHA stabilized Reinforced soil such as Maximum Dry Density, Optimum Moisture Content, Shear Parameter, Unconfined Compressive strength was investigate.
