Abstract: The purpose of the experimental investigation is to look into how bitumen's properties are affected by the addition of polythene trash. Due to its inability to degrade naturally and its long-lasting negative effects on the environment, polythene trash is a significant environmental hazard. In order to dispose of polythene trash sustainably, the study suggests adding it to bitumen, which is frequently used in road building. In this study, different amounts of polythene trash were added to bitumen (2%, 4%, 6%, 8%, and 10% by weight of bitumen) and their properties were compared to those of pure bitumen. Standard tests, such as those for penetration, softening point, ductility, and viscosity, were used to assess the bitumen's qualities. The study's findings demonstrated that bitumen's characteristics were enhanced by the addition of polythene trash. As polythene concentration rose, the penetration value dropped, suggesting that bitumen stiffness had increased. The modified bitumen's softening point grew, showing that its high-temperature characteristics had improved. The modified bitumen's ductility also increased, indicating a rise in its capacity to deform without breaking. Finally, the modified bitumen's viscosity increased, showing that its workability had improved. Overall, the study finds that mixing polythene trash with bitumen is a viable way to improve bitumen's qualities while lowering polythene waste's environmental impact. Due to the low cost and easy availability of polythene trash.
