A Study on Enhancement of Properties of Bitumen

Traffic volume and percentage of heavy vehicle have increased in last few decades, so it is in demand from pavement engineers to provide strong and durable pavements. There is a need to explore new and innovative material for extending the life of pavements to increase the predicted design life of the pavement. For that purpose we can use plastic waste in molten state for bituminous mix. Plastics are non-biodegradable, of course these are user friendly but not ecofriendly material and generally it is disposed by way of land filling which is hazardous for ground water table and or by incineration of materials which are hazardous for environment and mankind. The better way of disposal of waste plastic may be using it in molten state.In this paper behavior of bitumen mix with the use of plastic waste for construction purpose of roads and flexible pavements has reviewed. Generally bitumen is used as binder,such bitumen modified with waste plastic pieces and bitumen mix is prepared, which can be used for flexible pavement. This modified bitumen mix enhanced the various properties of bitumen and filler properties which are discussed in the paper.
