The rapid rate of urbanization in India has led to increasing plastic waste generation. This increase has resulted in a large amount of plastic waste, particularly plastic bags and PET bottles, being littered on the landscape of India. In this context, research has been carried out to contribute to the development of efficient policy approaches on plastic waste in India. Few policies have been enforced by the government to address the acute problem of littering in the country. The purpose of this project is to investigate the possibility of using Polyethylene Terephthalate as polymer additives in Bituminous Mix. The characteristics of PET-modified bituminous mix is obtained by fix mixing temperature, was investigated. The binders were prepared by mixing the PET in 2%, 4%, 6%, 8% and 10% (by the weight of optimum bitumen) with 80/100 penetration grade bitumen at temperature of 200-220 ºC. It may be inferred that PET-modified bituminous binders provide better stability when compared to conventional binders. Using PET-modified bituminous mix also contribute to the recirculation of plastic waste, as well as to the protection of the environment.

6. NEED FOR THE STUDY
Disposal of waste plastic is a major problem.
It is Non-Biodegradable.
Burning results in environmental pollution.
It mainly consists of low-density polyethylene.
Utility in Bituminous Mixes for road
construction.
Laboratory studies proving that waste plastic
enhances the property of the mix.
Disposal in an useful way.
