Abstracts: Over the past two decades traffic volume and percentage of heavy trucks have considerably increased and thus demanding from pavement engineers stronger and long lasting pavements. In order to increase the anticipated design life of the pavement, there is a need to investigate the application of new and innovative material for extending the life of the pavements. Bitumen is a useful binder for road construction. Different grades of bitumen like 30/40, 60/70 and 80/100 are available on the basis of their penetration values. The variation in daily and seasonal temperature demand improved road characteristics. Any improvement in the property of the binder is the needed. Everyday a tremendous amount of waste plastic bags are thrown on road side drains and choking the drainage system in cities. These plastics are either burnt or thrown along the shoulders of the road causing environmental pollution to the cities and other road side areas. If not recycled, their present disposal is either by land filling or by incinereation. Both the processes have certain impact on the environment. The present study is to explore the use of waste plastic in flexible pavements for road construction in developing countries. Moreover as the softened plastics have a binding property it is found that this molten plastic materials can be mixed with bitumen used for the rod construction.Past study also shows that molten plastic can also be used as coating over aggregate to be used in pavement construction and use of shredded plastic waste in bitumen for laying roads will help in preventing creation of pot holes, a very common problem of Indian roads. This study presents a research conducted to study the behaviour of Bituminous Mix prepared with "Plastic Waste- Bitumen" blend to be used in construction of flexible pavements for effective use in road construction industry which will result in improved road pavements and also safe disposal of waste plastic in particular to urban roads.
