摘要：

The increase in living standards and social and economic development over the past three decades has increased the demand of waste discarded in the environment. In the last five years due to the widespread application of polyethylene terephthalate (PET) waste, improper disposal has become a serious problem in the maintenance of an environmental balance. Some additives have been developed during the last decades in order to improve the mechanical properties of asphalt binder according the rheological properties. This research aims to evaluate the implementation of PET in a modified binder. PET was mixed with the percentage of 4, 5, and 6 wt% within a binder. It was found that progressive addition PET increased pulp consistency and improved its elastic response. Addition of PET showed promise in antiaging action, as the higher oxidation levels decrease modified binders.
