Incorporating Waste Plastics into Pavement Materials: A Review of Opportunities, Risks, Environmental Implications and Monitoring Strategies
AI summary Read the abstract
This review critically examines the opportunities and challenges of incorporating waste plastics into pavement construction, analyzing effects on mechanical properties, durability, and lifecycle performance. Special attention is given to the environmental risk of micro and nanoplastic generation and release during the pavement lifecycle, with evaluation of current monitoring methodologies.
The integration of waste plastics into pavement materials offers a dual benefit of enhancing road performance and mitigating the environmental burden of plastic waste. This review critically examines the opportunities and challenges associated with incorporating waste plastics in pavement construction, with an emphasis on their impact on mechanical properties, durability, and lifecycle performance of pavements. Special attention is given to the environmental implications, particularly the potential generation and release of micro- and nano-plastics during the pavement lifecycle. The paper further evaluates current monitoring and analytical methodologies for detecting plastic emissions from road surfaces and explores emerging approaches for minimizing environmental risks. By providing a comprehensive synthesis of existing knowledge, this review seeks to support sustainable practices and inform policy development within the frameworks of circular economy and environmental stewardship.
