Usage of Waste Plastic and Marble Dust in Flexible Pavements

In this present electronic age the development of the country is going at a very fast phase. The highway plays a major role in the development of the country and also improves the standards of living people. The aim of this project involves to lay the flexible pavements with waste materials with the intension of reducing cost and unavailability of conventional material. In flexible pavements the layers are the mixture of fine aggregate, coarse aggregate, filler and binder About 6.3 million metric tons of waste plastic has generated every year throughout the world. In that 9% of plastic has been recycled. using this waste plastic will increase the melting point of bitumen and marble dust helps the partial replacement of fine aggregate will helps the enhance the life of roads and also solve the environmental problems. Plastic roads would be boon for the hot & extreme climate where it will increase the durable and eco- friendly roads. The experiment portrays the use of plastic waste & marble dust comparing with and without usage in flexible pavements. Usage of waste plastic by blending with bitumen at various measurements of 1%, 1.5%, 2%, 3%, 4%, 5%, 6%, 7%, 8% by the weight of bitumen. The marble dust is partially replacement in the weight of fine aggregate with various measurements 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%. At finally plastic at 5%, marble dust at 20% is replaced during the mixing process of marshal stability test will give the better strength value. The experiments includes penetration, ductility, flash & fire point, softening point, stripping, specific gravity, water absorption test, viscosity, loss on heating, spot test, Marshall stability test.
