Recent Advances in Polymer-Modified and Plastic-Reinforced Asphalt: A Comprehensive Review of Performance, Rheology, and Sustainability
Summary
Researchers reviewed recent developments in polymer-modified and plastic-reinforced asphalt systems, synthesising findings on performance enhancement, rheological behaviour, and sustainability implications of incorporating recycled plastics and polymer modifiers into asphalt binders and mixtures.
Polymer modification of asphalt binders and the integration of recycled plastics in asphalt mixtures have become central strategies in enhancing pavement durability, reducing maintenance costs, and supporting sustainability goals. This review consolidates recent advances (2020–2025) in polymer-modified asphalt (PMA) systems, encompassing elastomeric and plastomeric modifiers, recycled plastic incorporation, performance indicators, rheological characteristics, and environmental implications. The work also identifies emerging trends in multi-factor aging studies, morphology analysis, and rheological characterization (e.g., MSCR, DSR, and BBR testing). Case studies and life-cycle assessments (LCA) demonstrate significant mechanical and ecological benefits of polymer and plastic modifiers, while compatibility and microplastic release remain active challenges.

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.
