ABSTRACT
Bottles, containers and packing strips etc. is increasing day by day. As a result amount of waste plastic also increases. This leads to various environmental problems. Many of the wastes produced today will remain in the environment for many years leading to various environmental concerns. Therefore it is necessary to utilize the
wastes effectively with technical development in each field.
PROBLEM FACED in field:
Road surface with neat bitumen can cause bleeding in hot climate, may develop cracks in cold climate.
Possess fewer loads bearing capacity and can cause serious damages because of higher axle load in present conditions due to rapid infrastructure development.
Useful life of bituminous overlays has reportedly declined 7-8 from average life of 5-6 years in the past to about 3-4 years at present as compared to average pavement life
India has to raise transportation system to a higher level both in terms of length and quality.
TESTS TO BE CONDUCTED:
Penetration test
Ductility test
Flash point test & Fire point test
Ring and ball test
Marshall Stability value test.
ADVANTAGES OF USING WASTE PLASTIC
Strength of the road construction is increased
Increase the road life
Polymer bitumen blend is a better binder when compared with the plain bitumen
Higher resistance to permanent deformation at higher temperature
Pavement performance
Protect environment and provide low cost roads.
