Plastics are convenient to use, however, they are not environmentally friendly because they are non-biodegradable. As the population grows, so does the amount of plastic waste in municipal solid waste. Plastic waste is becoming a huge concern since it is designed to withstand a variety of circumstances such as light, heat, chemicals, pathogens, and other factors in order to be useful in a variety of applications. One of the most practical and economical ways to dispose of waste plastic is to use it as a binder for Bitumen, which may be used to pave roads. The studies are carried out by mixing varying percentages (3, 6, 9 & 12)% of waste plastic with bitumen to see how it affects the properties of the bitumen. In comparison to conventional bitumen, the mixture had higher binding properties, stability, density, and water resistance. It also showed an improvement in fire point and flash point, indicating that it can withstand high temperatures. By replacing some bitumen with waste plastic, which is less expensive than bitumen, the entire construction cost can be reduced.
