Use of Waste Plastic Material in Bituminous Concrete Mixes

The quantum of plastic waste in is increasing due to increase in population, urbanization, development activities and changes in life style which leading widespread littering on the landscape. Thus disposal of waste plastic is become a serious problem globally due to their non-biodegradability and unacceptable view. Since these are not disposed scientifically & possibility to create ground soil-pollution and water-pollution. This waste plastic partially replaced the conventional material to improve desired mechanical characteristics& suitability for particular road mix. In the present paper developed techniques to use plastic waste for construction purpose of roads and flexible pavements has reviewed. In conventional road making process bitumen is used as binder for mixes. Such bitumen can be modified with waste plastic pieces and bitumen mix is made which can be used as a top layer coating of flexible pavement. This waste plastic modified bitumen mix show better binding property, stability, density, adheshive property and more resistant to water.
