This study explores the enhancement of strength and fatigue resistance in bituminous road pavements through the addition of PET plastic and polypropylene fibers. With the rapid increase in traffic loads and environmental challenges, conventional bituminous roads often suffer from issues like cracking, rutting, and fatigue under repeated stress. Utilizing waste materials like PET plastic from used bottles not only addresses these performance issues but also contributes to environmental sustainability by reducing plastic waste. The methodology involves a systematic approach starting with the selection of topic, literature collection, and material collection. PET bottles are shredded to obtain PET flakes, which are then added to the bituminous mix along with aggregates and viscosity grade (VG)-30 bitumen. Various proportions of PET (6–8%) with varying proportions of PPF are planned for attaining the best mix ratio so as to achieve tensile strength, flexibility, and overall durability, resulting in enhanced resistance to deformation, cracking, and rutting. The percentage of PET and PPF are determined by literature studies. The combination of PET plastic and polypropylene fibers creates a synergistic effect, reinforcing the pavement and extending its service life, particularly in high-traffic areas. This research offers a sustainable approach to road construction, suggesting that PET and polypropylene fiber reinforcement could be a valuable solution for achieving longer-lasting and eco-friendly pavements.
