ABSTRACT

Waste plastic from domestic and industrial sectors can be used in production of asphalt mix. Waste plastic which are mainly used for packing are made up of polyethylene, polypropylene and polystyrene. These materials softening vary between 110℃ to 140℃. These materials do not produce any toxic gases during the heating process. But softened plastics have tendency to form a film like structure over the aggregate when sprayed over the hot aggregate at 160℃. Plastic coated aggregate (PCA) is a better raw material for construction of flexible pavement. Then PCA was mixed with hot bitumen of different types and these mixes were used for road construction. PCA – Bitumen mix showed enhanced binding property and less wetting property. This sample showed higher Marshall Stability value in the range 18-20 KN. The load bearing capacity of the road is also increased by 100%. The road laid in 2002 using PCA – Bitumen mixes are still performing well. A detailed study on the performance of these roads shows that road constructed with PCA – Bitumen mix are performing well. This method is also eco-friendly and economical.
