The objective of this research was to improve the bearing capacity of the soil located on Kampung Juhut Street, Pandeglang Regency, which initially had a bearing capacity of 3.01%, through stabilization methods. The plastic powder was selected as an additive due to its non-cohesive characteristics, which counterbalance the cohesive nature of clay soil. The study aimed to identify the soil type and classification, evaluate the impact of soil physical properties, and examine the changes in unconfined compressive strength after incorporating plastic powder in proportions of 2%, 4%, 6%, 8%, and 10%, with curing durations ranging from 0 to 28 days. The results indicated that the soil belonged to the category of organic clay soils with moderate to high plasticity according to the USCS soil classification system. The plasticity index decreased from 22.9% to 12.2% at the 8% variation and 11.9% at the 10% variation. The initial unconfined compressive strength of the soil was 1.1 kg/cm2. The ...
Soil Stabilization by using Plastic Waste
Soil stabilization is a process which improves the physical properties of soil, such as increasing shear strength, bearing capacity etc. which can be done by use of controlled compaction or addition of suitable admixtures like cement, lime and waste materials like fly ash, phosphor gypsum etc. This new technique of soil stabilization can be effectively used to meet the challenges of society, to reduce the quantities of waste, producing useful material from non-useful waste materials. Plastic such as shopping bags is used to as a reinforcement to perform the CBR 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 (CBR) tests were carried out on randomly reinforced soil by varying percentage of plastic strips with different lengths and proportions. Results of CBR tests demonstrated that inclusion of waste plastic strips in soil with appropriate amounts improved strength and deformation behavior of sub grade soils substantially
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.

Soil adjustment is the procedure that improves soil physical properties, such as shear quality, bearing limit that should be possible through the use of controlled compaction or expansion of suitable admixtures such as cement, lime, sand, fly ash or geo-textiles, geo-synthetics, etc. Expansive soils such as black cotton soil are always causing problems with swelling, shrinking and unequal foundation settlement. Black Cotton soils with high swelling and contracting potential are one of India's major soil deposits as a result of changes in moisture content. The foundation is essential for any structure and it must be sufficiently able to help the whole structure. To establish the foundation, the soil around it plays a very important role in making plastic waste one of the world's biggest problems.. Utilization of plastic bottles and other plastic is exponentially expanding step by step because of these we are facing different ecological issues. The new method of soil adjustment can be adequately used to address the difficulties of society, to reduce the amounts of waste, creating valuable material from non-helpful waste materials. A review paper is introduced here to focus on soil stabilization by utilizing waste plastic items. Tests such as liquid limit, plastic limit, standard proctor compaction test, California bear ratio (CBR) test and direct shear test were performed check improvement in the properties of black cotton soil. Different contents of plastic waste % by weight varying by 0.5% 1.0% and 1.5% The black cotton soil was added and the optimal percentage of plastic strips was determined by the California bearing test ratio. 2%, 4%, 6%, 8% and 10% cement is used as a stabilizer by weight of soil.

KnE Engineering
The reuse and recycling rates for plastics are still below desirable values. The valorisation of plastic wastes that presently end in landfills or is incinerated can help to mitigate this environmental problem. There have been studies in soil improvement using plastic waste. Two types of plastic waste were used to assess their ability to improve soil properties for embankment construction and pavement layers. The selected plastic wastes are made from shredded package labels and ground bottles. The main properties of the soils were characterized. Three percentages of plastic waste were used, and the bearing capacity of the soil determined using CBR test (California Bearing Ratio). The results from the tests show that plastic waste stabilization leads to an increase in bearing capacity, expressed in CBR values, for low contents of plastic waste. This increase was more effective for high penetration values. Reduction in the bearing capacity was observed for higher plastic waste conten...

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.
