COMPARATIVE STUDY OF NORMAL ROADS WITH PLASTIC ROADS

In this paper the study of some of plastic waste materials we reuse by certain processing and use in road construction. Wrappers of betel nuts, chocolates, chips, hand bags, cold drink bottles and all other forms of plastic create significant environmental and economic problem. Plastics cannot be banned as it will result in usage of natural resources like paper, wood at a great extent. It is made up of various chemical elements and is regarded as a highly pestilent material which does not easily degrade in the natural environment after its usage. Waste plastics are made up of Polyethylene Polystyrene and Polypropylene. Temperature varying between 120°C-160°C gives the softening point of these plastics. They do not produce any toxic gases heating but the softened plastics have tendency to form a lamination or coating over the aggregate, when it is sprayed over the hot aggregate at 160°C. Utilization of waste plastic bags in bituminous mixes has proved that these enhance the properties of mix in addition to solving disposal problems. Plastic waste which is cleaned is cut into a size such that it passes through 2- 3mm sieve using shredding machine. So that one can have a step towards further detailed information about these materials and thus be able to implement on field which will definitely improve the level of construction.
