Effects of Microwave Heating and Long-Term Aging on the Rheological and Chemical Properties of Recovered Bitumen
Microwave heating of asphalt pavement is a promising technique to reduce the maintenance and increase the service life of materials through self-healing of cracks. Previous studies have shown that microwave heating technology at high temperatures could damage the bitumen of asphalt mixture, which is an unwanted effect of the crack-healing technique. In this study, the effects of microwave heating and long-term aging on the rheological and chemical properties of recovered bitumen were quantified using a frequency sweep test and Fourier Transform Infrared Spectrometry analysis, respectively. The main results indicate that microwave heating has no significant effect on the aging performance of G* and for aged asphalt mixtures. However, for newer bitumens, the rheological properties G* and show minor changes after microwave heating was applied. Overall, this study confirms that microwave heating is a potential alternative for maintenance of asphalt pavements, without severely affecting the rheological and chemical properties of bitumen.Open AccessEffects of Microwave Heating and Long-Term Aging on the Rheological and Chemical Properties of Recovered Bitumen
