Abstract: In this paper, the effect of using waste plastic and waste glass as a modifier in bituminous mix is investigated. HDPE waste plastic is used as modifier in bitumen of VG30 grade and waste glass bottle cullet as fine material in bituminous mix. The initial study was performed on virgin bitumen to investigate the physical characteristic of virgin unmodified binder then HDPE plastics are mixed in virgin bitumen to modify the physical characteristic of bitumen. To mix the HDPE plastic in bitumen 1700C blending temperature and 25mins blending time was adopted for manual mixing. Furthermore, Marshall Stability Test has been carried out on Conventional, HDPE modified mix, Glasphalt mix and HDPE Glasphalt bituminous mixtures. Optimum binder content was determined by using five different bitumen contents of 5%, 5.2%, 5.4%, 5.6% and 5.8% ,and optimum plastic content is by using five plastic contents of 0.2%, 0.4%, 0.6%, 0.8% and 1%, and optimum glass content is by four different glass content of 2.5%, 5%, 7.5% and 10%. Form the investigation of Marshall Stability test, 5.66% OBC, 0.6% OPC and 7.5% OGC is determined. HDPE modified Glasphalt mixture was prepared at optimum binder and Optimum plastic content with four different glass content. It is concluded that, with mixing of HDPE into both binder and mixtures properties are completely modified and shows good resistive nature temperature variation and seepage of water. HDPE modified Glasphalt mixture shows increased compressive strength than unmodified Glasphalt mixture. It is also concluded that waste plastic and waste glass can be used in bituminous mixture as a binder solution and fine material respectively. It is feasible to use and recycle waste plastic and glass in bituminous mixture as to protect environment and on economic point of view.
