Evaluation of Properties and Mechanisms of Waste Plastic/Rubber-Modified Asphalt
This engineering study investigated using a mixture of waste polyethylene plastic and recycled rubber tire material to modify road asphalt, improving its performance while diverting waste from landfills. The modified asphalt showed improved resistance to rutting and cracking. While not directly about microplastic health risks, using waste plastics in road construction could reduce the amount available to fragment into environmental microplastics.
