dc.description.abstract
Bio-oil, a waste material, has been increasingly utilized to rejuvenate aged bitumen. This study employs molecular dynamics method to investigate how bio-oil enhances the performance and rejuvenates aged bitumen. The analysis was conducted on blended models with varying proportions of aged bitumen, virgin bitumen, and bio-oil to determine their density and zero-shear viscosity. Mean square displacement (MSD) and radial distribution function (RDF) analyses were used to elucidate the rejuvenation mechanisms of bio-oil in aged bitumen. The results demonstrate that adding bio-oil effectively reduces the zero-shear viscosity of aged bitumen. This enhancement is attributed to increased molecular diffusion and reduced asphaltene aggregation. These findings offer new insights into using bio-oil-rejuvenated bitumen in pavement engineering to enhance sustainability.
