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.

Evaluation of eco-friendly asphalt mixtures incorporating waste plastic aggregates and additives: Magnesium, fly ash, and steel slag
Researchers tested adding waste plastic aggregate (WPA) to asphalt road mixtures at various concentrations, finding that 5% WPA content performs well and meets durability standards while also potentially reducing microplastic generation compared to exposed surface-layer applications. The study suggests recycled plastic can be practically incorporated into road construction to divert plastic waste from landfills.
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.
Plastic Recycling in Asphalt Concrete Pavements: Preliminary Observations from Hawaii’s Pilot Project
This paper presents results from a Hawaii pilot project testing asphalt mixes containing recycled plastic waste, evaluating their pavement performance. Incorporating plastic waste into road surfaces permanently sequesters it, preventing these materials from fragmenting into microplastics in the environment.
Environmental Impact Comparison Analysis between a Traditional Hot Mixed Asphalt (HMA) and with the Addition of Recycled Post-Consumer Polyethylene Terephthalate (RPET) through the Life Cycle Assessment (LCA) Methodology
This study conducted a life cycle assessment comparing traditional hot mixed asphalt with asphalt containing recycled PET plastic, evaluating environmental impacts of incorporating post-consumer plastic waste into road pavement construction.
Recycled Plastics in Asphalt Mixtures: A Systematic Review of Mechanical Performance, Environmental Impact and Practical Implementation
This systematic review evaluates using recycled plastics in road asphalt as a way to reduce plastic waste. The research found that incorporating recycled plastic can actually improve road durability while diverting waste from landfills. This approach matters for microplastic reduction because it locks plastic into road surfaces rather than allowing it to break down freely in the environment.
