A Review Literature on the Use of Waste Plastic to Improve Geotechnical Properties of Soil
Soil stabilization alters the physical properties of soil in order to improve its strength, durability, or other qualities to meet the engineering requirements. It can be achieved by adding suitable admixtures like cement, lime and waste material like fly ash, gypsum etc or by other suitable stabilization method. the cost of adding these additives has tremendously increased in past few years; there for there is need for the development of other kinds of soil additive such as plastic, bamboo etc and these new techniques of soil stabilization using plastic waste which can be effectively used to solve the challenges of society, thereby reducing the amount of waste plastic material. Use of polythene bags, bottles, and other plastic products is exponentially increasing year by year due to which we are facing various environmental problems. Therefore the correct way disposing off of the plastic waste without causing any ecological hazard has become a real challenge today. A review paper in presented here to focus on soil stabilization methods by using waste plastic products.
Utilization of Plastic Waste in Soil Reinforcement: A Review
International Journal of Technical Research & Science, 2020
Soil stabilization is one of the best methods for improving index properties, physical properties like shear strength, bearing capacity etc. of the soil. For soil stabilization various admixture such as cement, lime, fly ash, gypsum etc. can be used. But these admixtures are costly so their uses for soil stabilization are limited. In some research it is found that utilization of waste material like plastic, bamboo etc. are quite helpful in stabilization of soil. In present world there is scarcity of good soil which makes construction process difficult. So to enhance the properties of soil so that it can be used for various constructions there is need to add the suitable admixture in soil. These admixtures should enhance properties of soil and also be economical. The foundation is very important for any structure and it has to be strong enough to support the entire structure. For foundation to be strong the soil around it plays a very important role. A review paper is presented here to focus on soil reinforcement by using shredded waste plastic products. The tests such as liquid limit, plastic limit, standard proctor compaction test, California bearing ratio (CBR) test and unconfined compressive strength (UCS) have been conducted to check the improvement in the properties of problematic soil.
Utilization Of Bottled Plastic Waste For Strength Improvement Of Soil
2017
Due to an inefficient and faulty waste collection and transit system, a large amount of plastic waste fails to reach landfills or incinerators. Recycling plastic waste from water bottles has become one of the major challenges worldwide. The present study provides an approach for the use of plastic waste as reinforcement material in soil. To study effect of size and shape, plastic chips of different sizes (4mm x 12mm and 5mm x 15mm) had been used. A series of unconfined compression(UCC), direct box shear tests and swell pressure tests have been performed at four different percentages of fibers (0%, 0.5%, 0.75% and 1.0% by dry weight of soil) to determine stress-strain and swelling behavior of plastic waste mixed soil and the influence on plastic waste on shear strength of soil has been observed. The experimental results in the form of stress-strain response are presented. Based on experimental test results, it is observed that the strength of soil is improved significantly with addit...

Performance of plastic waste for soil improvement
SN Applied Sciences, 2019
Recycling plastic waste from water bottles has become one of the main challenges worldwide. The aim of this study is to recycle empty plastic water bottles as reinforcing material for the improvement of sandy soil. The laboratory tests were performed on both natural and reinforced sands with different plastic waste percentages: 0, 0.5, 0.75 and 1.0 of the dry weight of sand at relative density states of 30% and 60%. Direct shear box and the California Bearing Ratio, CBR tests were performed to determine the effect of the plastic waste on the shear strength and the penetration resistance of the reinforced sand. Test results indicated that plastic waste reinforcement contributed to the improvement of the shear strength and the CBR number of the reinforced sand. Higher shear strength and higher penetration resistance were obtained with plastic waste reinforcement. The optimum percentage of plastic waste required for enhancing the shear strength and the CBR number was found to be 0.75%. With the optimum percentage of plastic waste, the improvement in the shear strength and the penetration resistance of the reinforced sand increased to at least 9% compared to natural soil at relative density states of 30% and 60%.
Soil Stabilization Using Waste Plastic Materials
Open Journal of Civil Engineering, 2020
Expansive clay soils are the types of soils whose volume changes with the change in water content. They have a behavior of swelling and shrinking that is a serious hazard to structures built over them. Expansive soils are abundantly existing soil types in Ethiopia, particularly Addis Ababa. This paper shows the outcomes of an attempt to reinforce and stabilize expansive clay soil with plastic bottle strips. The plastic strips were prepared and added at three different mixing ratios (0.5%, 1% and 2%) by weight and in three different aspect ratios (5 mm × 7.5 mm, 10 mm × 15 mm, 15 mm × 20 mm). The experimental results showed that there was a significant improvement in shear strength parameters. The swelling and desiccation cracking behavior of the soil were also expressively reduced. There was a substantial reduction in the optimum moisture content and slight increment in maximum dry density. The optimum plastic size (aspect ratio) and plastic content that results in optimum result can be selected based on the importance of the selection parameter for a specified engineering work. Stabilizing expansive clay soils with waste plastic bottles simultaneously solves the challenges of improper plastic waste recycling that is currently a teething problem in most developing countries. The results obtained from this study favorably suggest that inclusion of this material in expansive soils would be effective for ground improvement in geotechnical engineering.
Strips of shredded plastic material were used as reinforcement inclusions at concentrations of up to 0.3% by weight. The effect of varying dimensions of the strips was investigated by using strip lengths from 15 mm to 45 mm and strip widths from 6 mm to 18 mm. Soil strength parameters were obtained for composite specimen from which analyses were carried out to identify the extent of soil improvement.Laboratory results obtained favourably suggest that inclusion of this material in sandy soils would be effective for soil reinforcement in geotechnical engineering.
Investigation of Stabilization of Expansive Soil with Plastic Bottle Strip Waste

Engineering soil stabilization is an operation of upgrading the strength features of the soil, by applying mechanical compaction and addition of stabilizing agents like lime, cement and demolished waste products like ceramics powder, etc. Implementation of alternative methods of improving soils that are favorable with the environment such as disposed waste, choir, synthetic fiber, etc. are becoming pleasing in civilized societies with the rising cost of admixture additives. This modern way of stabilizing soils can apply to meet the problems of society, to decrease the amounts of waste, to make useful material from disposed of materials. Thus, using bottles made from plastics as a soil improving agents is an economical application because of the low supply of good quality soil for construction. This thesis investigated the possible application of plastic bottles waste for stabilization of expansive clayey soils. The analysis was done by conducting soil strength test of Standard Proct...
Characteristic Properties of Plastic Wastes: Possibility of Reinforcing Material for Soil
2021
The current statistic shows that the percentage of plastic has significantly increased in the landfill and leads to environmental issues due to its non-biodegradable characteristic. However, these challenges can be turned into opportunities by reusing and recycling such waste for civil engineering applications. Hence, the focuses of this paper are to analyze the possibility of utilizing plastic waste in the soil reinforcement field using VOSviewer software and to evaluate the chemical, thermal, physical, and mechanical properties of the plastics (plastic straw, plastic bottle, and plastic bag). The data for this study was collected from the articles published in Scopus. Nevertheless, there are very limited articles that relate soil reinforcement with the thermal, chemical, physical, and mechanical properties of plastic waste. Therefore, this paper aims to evaluate the properties of plastic waste, which were plastic bottles, plastic bags, and plastic straw. The properties of plastic ...
