Performance and environmental impacts of waste plastic-modified asphalt pavement: a comprehensive review
This review examined recent research on using waste plastic to modify asphalt pavement and found that it generally improves road durability while reducing harmful emissions during production. However, challenges remain around plastic-bitumen compatibility and potential microplastic release during the pavement's lifetime, and the authors call for more standardized environmental assessments to ensure the approach is truly sustainable.

Plastic-Waste-Modified Asphalt for Sustainable Road Infrastructure: A Comprehensive Review
This review provides a comprehensive analysis of using waste plastics to modify asphalt for road construction, covering six major plastic types and both wet and dry processing methods. The study evaluated 42 peer-reviewed studies and found that integrating waste plastics into asphalt can enhance pavement performance while promoting circular economy principles, though environmental considerations such as microplastic release need further assessment.
Recent advances in the construction of sustainable asphalt roads with recycled plastic
This review examines the growing use of recycled plastics in road asphalt, tracing the practice back to the 1980s and identifying key challenges around performance, durability, and the risk of microplastic release from plastic-modified road surfaces. The authors conclude that while promising for waste reduction, more research is needed on long-term environmental impacts.
A systematic review on sustainable utilization of plastic waste in asphalt: assessing environmental and health impact, performance, and economic viability
Researchers systematically reviewed plastic-modified asphalt, finding that while recycled plastic waste can improve road performance in some cases, it also poses environmental health risks through microplastic release, carcinogenic compound emissions, and volatile organic compound off-gassing, with cost-effectiveness varying widely by plastic type and processing method.
A Comprehensive Review of Applications and Environmental Risks of Waste Plastics in Asphalt Pavements
This comprehensive review examined the use of waste plastics (PE, PP, PS, PVC, PET) as asphalt modifiers, covering modification mechanisms, incorporation techniques (wet and dry processes), and environmental risks. While waste-plastic asphalt can improve high-temperature stability and reduce landfill disposal, microplastic shedding from pavement wear remains an unresolved environmental hazard.
Engineering properties, microplastics and emissions assessment of recycled plastic modified asphalt mixtures
Researchers evaluated the mechanical performance and environmental impact of adding recycled low-density polyethylene and commingled plastics to hot-mix asphalt, finding reduced moisture resistance but also assessing microplastic release and emissions from these recycled plastic-modified road materials.
A bibliometric analysis and review on the performance of polymer-modified bitumen
This bibliometric review analyzed global research on polymer-modified bitumen, summarizing how polymer additives improve the physical and rheological properties of asphalt binders while identifying ongoing challenges with compatibility and aging degradation.
