Abstract: Repairing and maintaining pavements, necessitated by an ever-increasing population and traffic, is putting a strain on government budgets. When roads are not adequately enclosed, they frequently fail. Prioritising pavements in restoration plans that include cost- effectiveness, realistic ways to containment, performance assessments of materials and techniques, and sufficient case studies of pavement failures may be beneficial. Soil stabilization solutions, such as geosynthetics, geocells (for 3D confinement), rubber, and plastics, have recently become more popular, especially for reinforcing subgrade and subbase layers. Because these techniques reduce settlement and lateral deformation, pavements are more shear resistant, sustainable, and long-lasting. One terrible method of trash disposal is to burn old tires and plastic. An alternative idea, "GoeTyre Technology," has emerged as a result, suggesting the use of recycled tires in 3D printing rather than geocells. Using recycled plastic and polyethylene as a layer atop flexible pavement that repels water is another possibility. An additional focus of the research is to identify the variables that influence the success or failure of restricted and unconfined pavement restorations. The study's methodology included both laboratory and field testing, as well as finite element analysis in the "ANSYS" software package. The findings point to the use of used tires for three-dimensional confinement in combination with a 125-micron polyethylene impermeable layer as part of a revised pavement crust design for flexible pavements. In addition, thermo-geo plastic (TGP), a composite material, is being evaluated for use in flexible pavements as a cost-effective pothole filler. These solutions also address the issue of how to responsibly and affordably dispose of discarded plastics and tires. This indicates that these innovative methods of strengthening flexible pavements have significant potential as an eco-friendly and cost-effective option.
