The rapid growth of industries and the increasing population are significant sources of waste, with plastic waste being particularly hazardous due to its non-biodegradable nature. Bitumen, a key material in flexible pavement construction, benefits from the addition of plastic waste, which improves its water resistance, capacity, and stability. Research has shown that adding up to 10% plastic waste by weight to bitumen can enhance its mechanical properties. This study investigates the potential of using more than 10% plastic waste as a replacement for bitumen in pavement construction. The experimental methodology involves coating aggregates with a mix of single-use plastic waste and bitumen. The Marshall Stability test is used to evaluate the performance of various plastic waste proportions compared to conventional bituminous mixtures. Additionally, use of fly ash as fillers based on the weight of crushed stone aggregate shows promising results possibly for its pozzolanic action. This research explores the possibility of using optimal percentage of plastic waste which is more than 10% replacement that can be effectively incorporated into bitumen mixtures for sustainable road construction with economy.
