ClearUse of Waste Plastic as a Replacement for Bitumen in Road Construction
This review examines methods for incorporating waste plastic into road construction as an alternative to virgin bitumen and aggregates. Techniques like plastic-coated aggregates and plastic-modified bitumen improved road durability and weather resistance while diverting plastic from landfills. The approach offers a dual benefit of reducing plastic waste accumulation and decreasing the environmental impact of road construction.
Incorporating Waste Plastics into Pavement Materials: A Review of Opportunities, Risks, Environmental Implications, and Monitoring Strategies
This review examines the opportunities and risks of incorporating waste plastics into pavement construction materials, critically assessing performance benefits, environmental implications including microplastic release, and future directions for sustainable integration of plastic waste in road infrastructure.
Recycling/reuse of plastic waste as construction material for sustainable development: a review
Researchers reviewed how waste plastic can be incorporated into construction materials — as binders, aggregates, or cement substitutes in bricks, tiles, concrete, and roads — finding that plastic-modified materials often show competitive strength properties while simultaneously diverting plastic waste from landfills.
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.
Life Cycle Assessment of Road Pavements That Incorporate Waste Reuse: A Systematic Review and Guidelines Proposal
This systematic review examines life cycle assessments of roads built with recycled waste materials, including plastic. The research evaluates whether incorporating waste into road construction is truly more environmentally sustainable across the full life cycle. Using plastic waste in road building is one approach to keeping it out of the environment, though concerns remain about microplastic release from road surfaces over time.

Researchers evaluated the use of recycled plastic waste in road paver blocks in India, finding that incorporating recycled plastic improved block strength and weather resistance compared to conventional materials, offering a construction application for plastic waste.
A Comprehensive Review on the Use of Polyethylene Waste in Hot Mix Asphalt: Material Properties, Performance Enhancement, and Sustainability Perspectives
This review examines the use of low-density and high-density polyethylene waste as modifiers in hot mix asphalt, finding that PE incorporation can improve binder performance and pavement durability while diverting plastic waste from landfills. The authors assess material properties, environmental benefits, and economic considerations, positioning plastic-modified asphalt as a viable circular economy approach in road construction.
The Use of Waste Polymers in Asphalt Mixtures: Bibliometric Analysis and Systematic Review
This systematic review examines how waste plastics can be recycled into asphalt road mixtures, potentially reducing plastic waste in the environment. Researchers found that adding polymer waste to asphalt can actually improve road durability while diverting plastics from landfills and waterways. This matters because reducing plastic waste at the source is one way to lower the amount of microplastics that eventually break down and enter our food and water.
Plastic Road: A Sustainable Innovation in Civil Engineering
This study examines plastic roads as a civil engineering innovation that incorporates shredded plastic waste into asphalt mixtures as a partial bitumen substitute or aggregate modifier, assessing improvements to road durability and cost-effectiveness while addressing plastic waste accumulation. The review finds that plastic incorporation enhances structural performance and provides an environmentally beneficial disposal pathway for plastic waste.
Developing Sustainable Asphalt Mixtures Using High-Density Polyethylene Plastic Waste Material
Researchers evaluated asphalt mixtures incorporating high-density polyethylene (HDPE) plastic waste as a sustainable road pavement material, assessing whether recycled plastic can improve or maintain pavement performance while addressing plastic waste disposal.
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.
Utilization of Plastic Waste in Concrete Pavement
Researchers investigated the use of recycled high-density polyethylene (HDPE) plastic waste as an aggregate in concrete pavement mix designs, finding that incorporation of HDPE improved mechanical performance and durability while reducing landfill waste and energy consumption in the concrete sector.
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.
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.
