摘要：
The work presented in this paper aims to improve the rheological properties and ductility characteristics of aged (short-term) asphalt-binder using waste engine oil (WEO). The WEO was injected into the aged asphalt-binder as three rejuvenators, namely A, B, and C - with Rejuvenator A being the treated WEO only. Rejuvenator B consists of treated WEO and furfural extraction oil. Rejuvenator C consists of Rejuvenator B composition plus epoxy resin. The asphalt-binder physical, ductility, rheological, and morphological properties were measured using the standard penetration, softening point, ductility, dynamic shear rheometer, bending beam rheometer, and Fourier transform infrared spectroscopy tests, respectively. Overall, the laboratory test results, with Rejuvenator C exhibiting superiority, indicated that, if properly preprocessed and treated with additive modifications, WEO can be beneficially used to rejuvenate short-term aged asphalt-binders, which can be a significant milestone towards "green" asphalt and environmental conservatism.
