Study of Economics and Stability of Bituminous Road by using Waste Plastic

Abstract

Plastics are user friendly but not eco-friendly as they are non-biodegradable. The plastic waste in municipal solid waste is increasing due to an increase in the population. The disposal of plastic waste is becoming a major problem as they are intentionally made to resist to various conditions such as light, heat, chemicals, pathogen etc. to make it convenient to uses for various applications. The one of the efficient and cost effective disposal of waste plastic is using it as a binder for Bitumen which can be used for the pavement of road construction. The experiments are conducted by adding various percentages of waste plastic to Bitumen to evaluate the effect of this plastic on the properties of bitumen. The mixture shown the better binding property, stability, density and more resistant to water, it shown an improvement in the flash point and fire point also, implies that it can withstand high temperatures compare to pure bitumen. The total construction cost can also be reduced as some amount of bitumen is being replaced with waste plastic which is cheaper compared to bitumen.
