ClearPerformance Evaluation of Marshall Mixed Asphalt Concrete-Binder Course (AC-BC) Using Modified LDPE Waste Asphalt with the Wet Method
This study tested adding Low-Density Polyethylene (LDPE) plastic waste to road asphalt binder layers and found it improved pavement stability, with the best results at a 7% LDPE addition rate. While focused on road engineering rather than microplastic pollution, it is relevant because plastics incorporated into asphalt can fragment and shed tire-road microplastic particles into the environment over time.
Laboratory Studies on the Production of Asphalt Mixture Bad 22,4 with Pet (Plastic Bottle Fibers)
Researchers studied the properties of asphalt mixtures incorporating PET (polyethylene terephthalate) plastic waste as a modifier, testing how recycled plastic affects pavement mechanical performance, durability, and temperature resistance.

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.
The use of polyethylene terephthalate waste as modifiers for bitumen systems
Polyethylene terephthalate (PET) waste flakes were tested as a modifier for bitumen at various concentrations to improve road pavement performance. PET addition changed the rheological and mechanical properties of the bitumen, with certain concentrations improving resistance to deformation. Incorporating PET plastic waste into road materials offers a dual benefit of waste valorization and enhanced pavement durability.

The study found that only the 4% polystyrene addition met the VIM specification requirement, demonstrating limited viability for polystyrene as an asphalt modifier at higher concentrations.
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.
