Abstract
Asphalt binder as a by-product of petroleum is a finite resource. Hence, finding an alternative material for asphalt binder is a potential topic in the road engineering. Performance of compound-modified asphalt material at high temperatures, by waste cooking oil (WCO) and organic montmorillonite (OMMT) was investigated in this study, and the multi-scale correlation evaluation was conducted. The findings revealed that the bio-oil significantly reduces the barrier to rutting of asphalt materials within multi-scales, and rutting resistance was reduced with increased content. High-temperature performance can be regained or even better than that of base asphalt materials when WCO Bio-oil: OMMT is 1:1, and OMMT can compensate for the loss of high-temperature performance. Besides, the multi-scale correlation analysis shows that the Jnr3.2 index of OMMT composite modified bio-asphalt mastic, asphalt mixtures' resistance to rutting at high temperatures can be predicted using their short-term aging condition.
