Abstract

Abstract: Generally, the road network in Indiaand abroad carries both the passenger and freight transport. India has a roadnetwork of over 54, 72, 144 kilo meters and it is the world’s second largestnetwork.  Most of the investigationsstated that in India due to the increase of traffic day by day the applicationof wheel loads on the flexible roads are very high. So, the stability offlexible pavement is decreasing due to wheel load and deformation of roads isgetting increased day by day. To overcome this problem the properties of thebitumen on the roads should be improved by adding additives to the bitumenknown as bitumen modifiers. In India, the majority of the plastic waste mainlyconsists of polyethylene, polypropylene and polyolefins.  In this paper, the natural rubber is used asthe modifier to convert the normal bitumen to modified bitumen, because ofsimilar properties to that of plastic waste categorized under polyolefin.Marshal method of bituminous mix design was carried out for various percentagesof natural rubber in bitumen and various different mix design characteristicshas been determined.
