In 2022, researchers mixed waste PET bottles into asphalt; fatigue tests showed the modified pavement lasted longer than unmodified road surfaces

In an innovative study, researchers evaluated the performance of asphalt concrete mixed with waste polyethylene terephthalate (PET). Results demonstrated that incorporating a 10% volume of waste PET significantly enhanced resistance to cracking and deformation under load. Even various other mixtures adhered to traditional asphalt standards, which suggests a promising future for recycled materials in road construction.
