The use of waste polythene is increasing week by week. The waste polythene pollutes the environment, especially where there is no garbage collection and disposal system. A large amount of plastic collected from the tourist trekking regions and housing area are discarded or burned which releases harmful gases into the environment. The waste polythene collected from domestic and industrial sectors can be used in the production of plastics coated aggregate. Waste polythene, mainly used for packing and carrying any food. It’s made up of Polyethylene, Polypropylene, and polystyrene. Their softening point varies between 110 degree Celsius to 140 degree Celsius and if the wastes polythene is heated within this temperature range then they do not produce any toxic gases but the softened waste polythene have tendency to form a film like structure over the aggregate, when it is sprayed over the hot aggregate at 160 degree Celsius to 170 degree Celsius. The Plastics Coated Aggregates (PCA) is a better raw material for the construction of flexible pavement. PCA was mixed with hot bitumen of different types and the mixes were used for road construction.
