Experimental Investigation on Bituminous Pavement Using Construction Demolition Waste and Plastic Waste

Received Date:02 September 2022, Accepted Date:18 May 2023, Published Date:31 May 2023


Objectives: To develop an optimum bituminous mix by studying the properties of construction demolition waste aggregate (CDWA) and plastic waste as a partial replacement of natural coarse aggregate and bitumen. The performance and strength of the conventional bituminous mix and modified bituminous mix were studied using marshall stability test. Methods: Construction demolition waste aggregate (CDWA) is produced by crushing and screening old concrete from construction demolition waste, which is then used as a replacement for natural aggregates in pavement construction. This method helps reduce the need for new aggregate materials and conserves natural resources. The plastic waste is melted and blended with asphalt to create a more durable and weather-resistant material. This method reduces the amount of plastic waste in landfills and provides a sustainable solution for pavement construction. Findings: Based on the research, the optimum mix proportion of bituminous mix is found as 10% plastic waste blended with 15% construction demolition waste aggregate. The results of marshall stability test have shown significant increase in strength of pavement mixes by adding construction demolition waste and plastic waste. Novelty: The novelty of this study lies in its approach to addressing two major environmental issues simultaneously: waste management and sustainable construction practices. The study proposes a solution to reduce the amount of natural resources such as natural coarse aggregate and bitumen by blending alternate recyclable waste materials such as construction demolition waste aggregate and plastic waste shredded from waste bottles.
