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.
