Abstract: A significant portion of the total municipal solid waste (MSW) generated in India consists of Plastic waste.As per the recent estimates, approximately Ten thousand tons per day (TPD) of plastics waste is generated. As plastics are not biodegradable, it is better to use the waste plastic for some beneficial purposes. The main objective of present work is to study the benefit of PET (Poly Ethylene Terapthalate) polymer modified bituminous mixes performance. Various percentages of PET are used for preparation of mixes with a selected aggregate grading as given in the MORTH &IRC Code. The role of PET in the mix is studied for various engineering properties by preparing Marshall Samples of DBM mixtures with and without addition of polymer. Various Properties such as stability, flow , unit weight and air voids are used to determine optimum polythene content for the two grades of bitumen VG10 (80/100) and VG 30(60/70). The physical and mechanical properties of PET modified and conventional binder mixes are evaluated. These Mixes are compacted using Marshall. Indirect tensile strength ratio tests were conducted and compared.
