Abstract-
Plastics wastes are increase in developing countries with increase in population. So there is a need to utilize these non-biodegradable wastes in alternate way to make them environment friendly. The work reported through this paper is an experimental work conducted on mix design of semi dense bituminous concrete (SDBC) using conventional aggregate and waste plastic coated aggregate. Job mix formula for SDBC is evolved in accordance with MoRT&H (Ministry of Road, Transport and Highways) specification. Waste plastic is added in the mix design as 5%, 10% and 15% of the bitumen content. Effect of waste plastic in the mix design of SDBC mix was studied through Marshall Stability test. Inclusion of waste plastic in the bituminous mix could reduce optimum bitumen content from 5.42% to 5.24%.
