Rainmaker 2021 Start-up: Sustainability assessment of recycled plastic based road pavements

Project: Research

Project Details

Description

Around 6 billion tons of plastic waste was generated during 1950-2018; among that, 79% was landfilled, 12% was incinerated whereas only 9% was recycled. In addition, both incineration and landfilling are hazardous practices. It is anticipated that if this trend of waste plastic generation continues, there will be approximately 12,000 million metric tons of plastic waste in 2050, causing substantial environmental concerns. Therefore, this study aims to investigate the use of waste plastic in road pavements. Various contemporary researches show that polymer or plastic modified bitumen offers a range of benefits over conventional bitumen in road pavements, such as, reduced thermal susceptivity, greater resistance to rutting (at high temperature), better strain tolerance (at lower temperature), improved relaxation properties, betterments in fatigue resistance, improved bitumen-aggregate bonding, reduced stripping, enhanced pavement durability and lower life cycle costs. Therefore, this project aims to investigate the life cycle environmental sustainability assessment of recycled plastic plus bitumen blends to be deployed in road pavements. Various environmental footprints such as greenhouse gas emission, energy use, ozone depletion, resources use, material scarcity, fossil resources scarcity, as contributed by the recycled plastic plus bitumen blend, will be evaluated in this context. Findings from the study will demonstrate the eco-profile of the recycled plastic based bitumen grades in comparison to the conventional bitumen.

The research grant therefore will support us to buy needed materials and database or software, lifecycle consultancy, and to buy out time of personnel as necessary. Preliminary research findings based on the product development will position the investigators to a successful preparation of competitive funding application.
