Abstract - Soil is a very important part of the earth's
ecosystem. However, the earth is becoming increasingly polluted as a result of human waste plastic dumping. For engineering purposes, black cotton soil is a difficult material to stabilize due to its great capacity for shrinking and swelling as a result of changes in moisture content. When compared to other types of soil, it will reduce the stability and shear strength of black cotton soil. This project study describes the stabilization of black cotton soil using PET (Polyethylene Terephthalate) powder, which is effectively used to address societal concerns such as reducing plastic waste and improving soil physical qualities such as shear strength Moisture content. PET (Polyethylene Terephthalate) powder is used in different proportion 0%, 0.2%, 0.4%, 0.6%, 0.8% and 1%. Then index Properties test, Standard Proctor, Moisture Content and Direct shear test are conducted to find the properties of soil which will increases the strength of soil.

INTRODUCTION Soil stabilization a general term for any physical, chemical, mechanical, biological, or combined method of changing a natural soil to meet an engineering purpose. Black cotton soils are beneficial to agriculture, but they have shown to be a major threat to structures built on them. These soils have a high swelling capacity due to water ingestion during the monsoon season and a low shrinkage capacity due to evaporation during the summer season. The presence of the mineral montmorillonite is responsible for the swelling and shrinkage. The constructions built on these soils incur fissures as a result of the significant swelling and shrinking, rendering them unsuitable for foundation. As a result, there is a need to improve the strength of black cotton soil so that it can be used as a foundation material. To improve soil strength values, soil stabilization with plastic trash can be used in embankments and road pavement layers. The use of plastic garbage to stabilize the

soil produced an unusual result, with an increase in soil strength parameters assessed in several experiments. However, some researchers claim that the results vary depending on the kind of soil, and that waste plastic stabilization may reduce some strength values. 2. OBJECTIVES
To conduct Direct Shear Test (DST), Optimum Moisture Content (OMC), Maximum Dry Density (MDD), consistency (Liquid limit, Plastic limit, Shrinkage limit) and sieve analysis of soil.
To conduct Direct Shear Test (DST), Optimum Moisture Content (OMC), Maximum Dry Density (MDD), consistency (Liquid limit, Plastic limit, Shrinkage limit) and sieve analysis for 0%, 0.2%, 0.4%, 0.6%, 0.8% and 1% of plastic powder.
Comparison between different percentage.
2.1 Scope of Project The scope of present work includes addition of plastic bottle powder to the locally available soils to enhance the engineering properties. The work presented in this paper aims to investigate the improvement of soil properties such as shear strength, maximum dry density OMC, MDD and Direct Shear strength values by adding powder from plastic bottles. A series of laboratory tests are conducted on both untreated soils as well as on plastic reinforced soil to compare the improvement of soil properties. List of experiments conducted in laboratory as per IS Codes. 3. MATERIALS Black Cotton Soil Soil used for project is taken fromnA/p Kambleshwar Tal – Phaltan Dist – Satara. Which is about 10 km from PES’s College of Engineering, Phaltan. The soil is collected from certain ground level. The disturbed soil sample is then transported to the geotechnical laboratory of PES’s COE Phaltan.
