Polyester (PET) is used in asphalt binder to improve the sustainability and performance of the road. Modification of
asphalt has become a serious demand these days due to performance requirements caused by significant traffic and
heavy vehicles. Asphalt alone cannot bear the stresses. The Marshall Mix design method is used for testing treated and
untreated asphalt samples. The properties of all asphalt samples were compared. The best combination of asphalt and
PET for best performance is based on the study of PET content used in the mix of PET/Asphalt, i.e., 0%, 2.5%, 5%,
7.5%, and 10%. The following tests were performed on the asphalt samples for various aspects of performance: stability
test, flow test, air voids, voids filled with asphalt (VFA), voids in mineral aggregate (VMA), and OAC. Polyester waste is
utilized in road construction which has been proved helpful to improve the performance of conventional road
construction and provide reliability in a sustainable approach. An asphalt grade of 60/70 was taken for evaluation.
