Aging of asphalt binders occurs when oxidation takes place in the binder, and this in turn causes the deterioration of pavement. This paper presents the effect of aging on 60/70 penetration grade asphalt binder incorporated with polyurethane (PU) in terms of chemical interaction, morphological and wettability properties. The chemical characteristics of the base binder (BB) and polyurethane modified binder (PUMB) was evaluated using Fourier Transform Infrared while the morphological properties were analyzed using Raman Spectroscopy. Contact angle test was performed to determine the wettability of PUMB over the aggregates. In this study, the BB is modified with 3 wt PU. Rolling Thin Film Oven and Pressure Aging Vessel tests were conducted to simulate the short-term aged and long-term aged of the samples. Results showed that the addition of PU to BB has no significant effect on the chemical interaction in the modified binder before and after aging. The incorporation of PU and the aging of modified binder resulted in a reduced bee-structure in the BB, which in turn reduced the wettability of the asphalt binder. The incorporation of PU to the BB improved the oxidative aging of the binder. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
