The test results under the circumstances are provided to evaluate the change in soil strength characteristics. In the aspects of shear strength, friction angle, and cohesiveness, it was determined that soil samples containing 5-9% plastic strips performed better than soil samples containing no plastic strips. The composition of discarded plastic bottle strips has a considerable influence on the development of soil strength. On the other hand, the inclusion of the plastic strip enhanced the permeability of black cotton-reinforced soil. In addition, this innovative approach may be utilized to successfully address socioeconomic issues, such as the recycling of waste materials read more..
