Preservation of road infrastructure requires a systematic approach for the good performance of roads keeping in mind the future condition and maintenance scenarios. Now-a-days pavements are subjected to various kinds of loading which affects the pavement performance condition that causes various distresses. These distresses include rutting, fatigue cracking, and temperature cracking. Looking forward to the environmental condition, complete ban on plastic cannot be made. Thus, using of plastic as an innovative technology not only strengthened the road construction but also increase the road life. This study includes the results of the various laboratory tests conducted on bitumen, aggregate and bitumen-aggregate plastic mix.This study investigates the rheological properties of bitumen (asphalt) binder penetration grade 60-70 modified with an additive Polyethylene Terephthalate (PET). Bitumen is visco-elastic material where temperature and rate of load application have a great influence on their performance. The properties evaluated include the rheological properties of the modified bitumen binder. These properties were penetration by Penetro meter and softening point by Ring and Ball test. The binders were mixed with various percentages of waste PET bottles 5, 10 and 15% by weight of bitumen binder.
