(VG40), for constructing low-budget roads is discussed as an alternative to conventional, expensive polymer modified bitumen (PMB). The increase in economic growth and changes in consumption and production patterns have led to the generation of various wastes, including plastic waste, tire rubber waste, fly ash, among others, polluting urban areas. In the current study VG40 is mixed with the two different polymer wastes i.e., PET bottles and rubber tire scrap powder. The preliminary tests were conducted on VG40 mixed with 2, 4, 6, 8, 10% of combined waste. The study demonstrates that adding 6% waste by weight to hot 30/40 pen grade bitumen enhances stiffness, resistance to high-temperature deformation, elasticity, and cohesiveness at the micro level.
Key Words: VG40; Tire rubber; Waste plastic; Elastic recovery; PET bottles. 1. Introduction The need for transportation has gradually increased in tandem with the growth of the global population. Highways are still the world's most frequently used transportation method for both passenger and freight transit since they provide access to almost everywhere. Unfortunately, the growing demand for transportation also has a negative impact on the speed at which roadway pavements deteriorate. Improving the quality of materials used to build roadways is the main strategy utilized to prevent pavement deterioration. Bitumen is a building substance used in flexible pavements as a binder. Depending on the temperature and vehicle speed, bitumen exhibits different behaviour. At high speeds and low temperatures, bitumen behaves more like an elastic solid. Thermal cracks are the most common type of degradation that occurs under certain circumstances. Wheel tracking is the most frequent type of deterioration because bitumen behaves more like a viscous liquid at low speeds and high temperatures. Fatigue cracks are the most common form of breakdown when bitumen exhibits viscoelastic properties under typical ambient conditions and average speed values. Various studies have been conducted on the properties of hotmix asphalt (HMA) used in flexible pavements. It is common to modify bitumen with polymer-based additives, and there are numerous studies on this subject in the literature. Waste thermoplastics are currently being investigated as an option for bitumen modification due to the high cost of polymer-based additives. 1.1 Previous Studies Shamim. S. and Vikram. A. (2023) studied that the addition of Tio2 to the plastic waste samples led to further improvement in the values of both Marshall stability and indirect tensile strength. The optimal amount of Tio2 addition was found to be 1% of the total weight of the sample. Beyond this amount, the values of both Marshall stability and indirect tensile strength decreased. Russo and Oreto (2022) use of plastic waste and jet grouting waste as fillers in the production of hot asphalt mastics. The results showed that plastic waste had the best environmental performance. Vangari M. and Poloju K. K. (2022) polymer-modified bitumen in recycled asphalt pavement (RAP). The research involved conducting various laboratory tests by replacing bitumen with different polymers including polypropylene, polyethylene, and RAP material.
