Use of Waste Plastic and used Rubber in Bituminous Pavement

An upswing in various types of productions together with population growth has resulted in a massive increase in production of various types of waste material world over creating a problem of its disposal in Eco-friendly way. To deal with the problem here an attempt is made to study the use of waste as an alternative to conventional material along with partial replacement of bitumen with plastic and used rubber by the wet mix process. In the highway infrastructure, a large number of originate materials and technologies have been invented to determine their suitability for the design, construction and maintenance of these pavements. Plastics and rubbers are one of them. Also considering the environmental approach, due to excessive use of polythenes in day to day business, the pollution to the environment is enormous. Numbers of laboratory tests were conducted using marshal stability testing machine to check the suitability used rubber and plastic as an alternative to conventional materials. The main aim of this study is to focus on using the available waste recycled plastic materials and waste rubber tires present in abundant that can be used economically and conveniently. The results obtained in laboratory investigation indicate not only the increase in strength but also a considerable reduction in cost is seen. From the experimental work, it is clear that the properties of laboratories designed bituminous mix are much more superior to those of the conventional bituminous mixes. The use of these materials as a road construction proves Eco-friendly, economical and use of plastic will also give strength in the sub base course of the pavement and can be effectively used in practical applications.
