Soil stabilization means improving soil stability or loadability by using controlled compaction, dosing and / or adding suitable additives or stabilizers. Soil stabilization is any process that improves soil physical properties, such as increased shear strength, support capacity, etc. Which can be made by controlled compaction or addition of suitable additives such as cement, lime and waste materials such as fly ash, phosphogenesis, etc. The cost of introducing these additives has also increased in recent years, which opened the door extensively for the development of other types of additives for floors such as plastics, bamboo, etc. This new soil stabilization technique can be effectively used to meet societal challenges, reduce waste quantities and produce useful material from non-useful materials. The use of plastic products such as polyethylene bags, bottles, etc., is increasing day by day, giving rise to various environmental concerns. Therefore, the disposal of plastic waste without causing any ecological hazard has become a real challenge. Therefore, the use of plastic bottles as soil stabilizer is an economical use, since there is a shortage of good quality soil for embankments. This project includes the detailed study on the possible use of waste plastic bottles for soil stabilization. The analysis was carried out by plate loading tests reinforced with layers of plastic bottles filled with sand and bottles cut in halves placed in intermediate and third positions of the tank. Comparison of the results of the tests showed that the cut bottles placed in the middle position were the most efficient to increase soil resistance. The optimal percentage of plastic strips in the soil was determined by the California Bearing Ratio Test and the use of this percentage of plastic plaque loading test was also performed. The size and content of plastic waste bottle strips have a significant effect on improving soil resistance.
