The combined utilization of waste cooking oil (WCO) and reclaimed asphalt pavement (RAP) is attractive for economic, environmental, and energy benefits. However, the quality stability of WCO is poor due to its wide sources, which limits the further development of WCO recycled RAP. In this study, the classification method of WCO was proposed according to the mol. weight difference of its chem. components, and WCO was classified into three categories including light components (LC), intermediate components (IC), and heavy components (HC). Meanwhile, the characteristics of these three WCO components and their effects on the physicochem. properties of aging asphalt were investigated comprehensively. The exptl. results show that the softening ability of different components of WCO on aging asphalt is mainly determined by their mol. weight and thermal stability. Furthermore, LC rich in Me palmitate is easy solidification and volume expansion at the low temperature, which is not conducive to the repair of low-temperature ductility of aged asphalt. The chem. property analyses of recycled asphalt indicate that there is no chem. reaction between the components of WCO and the aging asphalt. The phys. dilution ability of WCO components on carbonyl index, sulfoxide index, and high mol. weight substances of aging asphalt is pos. correlated with their mol. weight In addition, HC contains chem. substances similar in composition to asphalt, which has the most obvious effect on the colloidal structure of aging asphalt. Overall, the classification method for WCO and related findings found in this study provides a reference for ensuring the quality stability of WCO and its industrial application in the recycling of aged asphalt.
