Ministry of Environment and Forest (MOEF) and Central Pollution Control Board (CPCB) inducted rules for plastic waste management and recommended also possible recycling of waste as far as possible. For a sustainable resource management practice, plastic waste are being recycled in many ways.plastic waste management institute reported about 55% of waste plastic are effectively being utilized in energy recovery and feedstock recycling. Polyethylene Terephthalate (PET) materials are used in bottles, food packaging and carpets The present paper describes the status on uses of various waste plastic material for also for the parameters improvement of soil in terms of its Use of natural fiber in civil engineering for improving soil properties is advantageous because they are cheap, locally available, biodegradable and eco-friendly. The natural fiber reinforcement causes significant improvement in tensile strength, shear strength, and other engineering properties of the soil. Over the last decade the use of randomly distributed natural and synthetic fiber has recorded a tremendous increase. Every year, 7.2 million tons of hazardous waste is produced and its disposal is becoming a major issue and about one km2 of additional landfill area is needed every year. Indian government spends about Rs 1600 corer for treatment & disposal of these wastes. In addition to this, industries discharge about 150 million tons of high volume low hazard waste every year, which is mostly dumped on open low lying land areas. Keywords: Natural waste plastic material, Different types of soil, and Modified Proctor compaction test apparatus. INTRODUCTION In this study, plastic such as Polyethylene, Bottles,Food packaging and shopping bags etc is used to as a reinforcement to perform the studies while mixing with soil for improving engineering performance of sub grade soil. Plastic strips obtained from waste plastic were mixed randomly with the soil. A series of California Bearing Ratio () tests were carried out on randomly reinforced soil by varying percentage of waste plastic material with mix different proportions. Results of tests demonstrated that inclusion of waste plastic material in soil with appropriate amounts improved strength and deformation behavior of sub grade soils substantially. The proposed technique can be used to advantage in embankment/road construction, industrial yards etc [1,2]. In this study a number of experiments were conducted on locally available soil reinforced with natural waste plastic material. Soil samples for value tests were prepared at its maximum dry density corresponding to its optimum moisture content in the mould with and without reinforcement. The waste plastic material taken as 0.25%,0.50%,0.75% and 1.00% by dry weight of each soil sample and corresponding to each plastic content and soaked tests were conducted in the laboratory [3,4]. *Corresponding Author 304

2 WHAT IS CONSTRUCTION OF WASTE PLASTIC MATERIAL Plastic waste when mixed with soil behaves like a fiber reinforced soil. Plastic-waste materials are produced plentifully such as polyethylene terephthalate (PET) plastic bottles, polypropylene of plastic sack, and polypropylene of carpet. But such materials have been used little for engineering purposes. These plastic wastes in the form of randomly mixed with soil and the behavior of the soil is similar to fiber reinforced soil. Soil reinforcement technique is one of the most popular techniques used for improvement of poor soils. Metal strips, synthetic geotexitle, geogrid sheets, natural geotexitle, randomly distributed, synthetic and natural fibers are being used as reinforcing materials to soil. Further, the soil reinforcement causes significant improvement in tensile strength, shear strength, other properties, bearing capacity as well as economy. This is a relatively simple technique for ground improvement and has tremendous potential as accost effective solution to many geotechnical problems [5]. METHODOLOGY Soil material: The soil types in the study were Expensive soil(block cotton), Silty-clay soil and sandy soil. Soil collected from the Jabalpur Engineer College campus and Hostel area was used in this study for Laboratory testing. the maximum dry density and maximum water content of soil as determined from the relative tests. Nature waste plastic material: The waste plastic material were sourced from a local market was used in this study for Laboratory testing of different percentage with different types of soil. The tests were conducted at various waste plastic contents of 0.0%,0.25%,0.50% and 1.00% [6].

Based on the laboratory studies carried out in this work, the conclusions are as below: 2. As the percentage of plastic waste in soil samples increases, the maximum dry density increases, thereby increasing the value. Hence natural waste plastic material was mixed along with the soil, to increase its maximum dry density. 3. Increase in percentage of waste plastic material resulted in increase of maximum dry density and value. Hence Plastic was found to be suitable for pavement subgrade. 4. Plastic mix with selected soil maintains the value within the required range. 5. The study after several experiments, found following significances in using Waste plastic material or strips as supporting/stabilizing agent. a. The addition of reclaimed plastic waste material to local soil increases the. b. The maximum improvement in is obtained while using 1.0% plastics strips having aspect ratio 3. c. The value at 0.25 & 0.50% plastic minimum increase. 6. The reinforcement benefit increases with an increase in and percentage of plastic material/strip content up to certain limit, and beyond that it increase its strength. a. The maximum value of a reinforced system is approximately 1.3 times that of an unreinforced system. We can therefore conclude that base course thickness can be significantly reduced if waste plastic strip is used as soil stabilizing agent for sub-grade material. This suggests that the strips of appropriate size cut from Copyright 2013 Published by IJESR. All rights reserved 307

5 reclaimed plastic wastes may prove beneficial as soil reinforcement in highways. Sub-base if mixed with locally available Block cotton, silty clay soil and Sandy soil in appropriate quantity. However further study is needed: i. To optimize the size and shape of strips and increasing its percentage content. ii. Large scale test is also needed to determine the boundary effects influence on test results. iii. The plastic should be uniformly mixed with soil for an effective result. b. The plastic inclusions can also improve the load bearing capacity and settlement characteristics of the selected soil material. Additionally, introduction of perforations on the plastic material further aids in the interaction between the soil and plastic thereby boosting the soil s strength properties. However, a better understanding of the interaction mechanism in soils reinforced with the plastic material would be essential to properly document the engineering behaviour of the soil-plastic composite.even though this method is much effective in stabilization; ; it can be used as an effective method in disposing waste plastic materials. ; it can be used as an effective method in disposing waste plastic materials. NEEDS & ADVANTAGES 1. It improves the strength of the soil, thus, increasing the soil bearing capacity. 2. It is more economical both in terms of cost and energy to increase the bearing capacity of the soil rather than going for deep foundation or raft foundation. 3. It is also used to provide more stability to the soil in slopes or other such places. 4 Sometimes soil stabilization is also used to prevent soil erosion or formation of dust, which is very useful especially in dry and arid weather. 5. Stabilization is also done for soil water-proofing; this prevents water from entering into the soil and hence helps the soil from losing its strength. 6. It helps in reducing the soil volume change due to change in temperature or moisture content. 7. Stabilization improves the workability and the durability of the soil.
