<abstract xmlns="http://www.w3.org/1999/xhtml"><p>This study considers the use of polyethylene terephthalate (PET) waste for modifying asphalt concrete. In the study, the optimum bitumen content of asphalt concrete was replaced with 4%, 6%, 8%, 10%, 12%, 14% and 16% of PET waste; the Marshall test was conducted on the samples. A comparison of the unmodified and PET-modified asphalt concrete showed that the stability of the modified asphalt concrete was reduced. The maximum stability for the PET waste-modified asphalt concrete was recorded at a content of 12% PET waste. This gives about a 20.4% reduction in stability. The study reveals that the addition of PET waste to the asphalt concrete causes a reduction in the flow value except with the addition of 14% and 16 % waste. This implies that the introduction of PET waste could improve the permanent deformation resistance of asphalt, although there is concern about a reduction in fatigue resistance.</p></abstract>
