Any procedure that enhances the physical characteristics of soil, such as raising its shear strength or bearing capacity, is referred to as soil stabilization. This can be accomplished through the use of controlled compaction or by adding the right admixtures, such as cement, lime, and waste products like fly ash and phosphogypsum. Since good quality soil for embankments and pavements is difficult to come by, using plastic bottles as a soil stabilizer is an inexpensive use of waste materials. This project entails a thorough investigation into the potential use of used plastic bottles for stabilizing soil. In order to conduct the analysis, a CBR test was performed on soil that had been reinforced with layers of plastic bottles at varying percentages (0.5%, 0.7%, and 0.9% for distinct soils). The CBR test is carried out on red, loamy soil and black cotton soil. It is discovered that the strength of the soil is increased, resulting in a bearing ratio of 3.3 for black cotton soil and 0.7% for red soil after the addition of plastic stripes. Additionally, loamy soil's strength is boosted by adding 0.7% of plastic strips, resulting in a bearing ratio of 2.9.
