USE OF PLASTIC WASTE WITH PARTIALLY REPLACEMENT OF BITUMEN IN FLEXIBLE PAVEMENTS

Abstract

Disposal of huge amount of various types of waste materials like plastic, polythene bags, bottles and
rubber tyres etc, which are generated in huge quantity and causes harmful environmental effect after their disposal has a
big challenge for the recent days. This study attempts the utilization of these waste materials as partial replacement of
bitumen to develop a modified binder, for making bituminous concrete mix. To simulate with the field conditions,
‘Marshall Stability test’ was performed on the samples prepared by partially replacing ‘Optimum Bitumen Content’ with
waste plastic (2%, 4%, 6% and 8%). In this Research we focused on scrapping of plastic waste is a significant issue due to
its non-bio-degradability. Laboratory testing results specify that by using waste materials, bituminous concrete of required
strength and density can be acquired and an environment friendly green pavement can be prepared with less material
cost. The use of waste commodity plastics in binder modification carries the advantage of a cheap and effectual means of
enhancing conventional bitumen binder performance characteristics and is an alternative way to utilize plastic waste. This
waste plastic with modified bitumen mix show better binding property and good stability value.
