Asphalt pavements are an essential part of the transportation infrastructure that is necessary for Marine environment growth. This research delves into the novel incorporation of recycled plastics into VG30-grade bitumen for use in road building, including polyethylene terep thalate (PET), high- densitypolyethylene (HDPE), and polyvinyl chloride (PVC). Improving infrastructure resilience and reducing environmental effect through the usage of plastic waste are two challenges that this study seeks to solve. Specifically, it seeks to optimize plastic proportions in order to increase pavement durabilityandsustainability. The Marshall Stability (MS) test and other rigorous laboratory experiments provide the basis of an extensive experimental strategy that examines different asphalt compositions. According to the results, the optimal mix for maximum MS is 3.0% waste plastic, made entirely of PET, with 5.5% bitumen. This formulation showcases substantial performance improvements achieved by selective plastic inclusion, and it outperforms standard asphalt mixes in terms of stability by an impressive 73.07%.
