Abstract
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. Marshall Mix design method is used for testing of treated and untreated asphalt samples. The properties of all asphalt samples were compared. The best combination of asphalt and PET for best performance 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.
