Molecular dynamics evaluation of activation mechanism of rejuvenator in reclaimed asphalt pavement (RAP) binder

Incorporation of rejuvenators can promote the rejuvenation of heavily oxidized asphalt when high proportion of reclaimed asphalt pavement (RAP) is used. However, there are few atomic-scale interpretations on the rejuvenating effect of rejuvenator in RAP and its activation mechanism during the blending of aged and virgin asphalt. This study focuses on the atomic modeling of rejuvenation behavior of oxidized asphalt. Three types of asphalt models...
