Ren, S. (author), Liu, X. (author), Gao, Y. (author), Jing, R. (author), Lin, P. (author), Erkens, S. (author), Wang, H. (author)This study aims to multiscale investigate the effects of rejuvenator type, temperature, and aging degree of bitumen on the diffusion behaviors of rejuvenators (bio-oil BO, engine-oil EO, naphthenic-oil NO, and aromatic-oil AO) in aged binders. The molecular dynamics (MD) simulation method is performed to detect the molecular-level diffusion...journal article 2023

Ding, Heyang (author), Wang, Hainian (author), Qu, Xin (author), Varveri, Aikaterini (author), Gao, Junfeng (author), You, Zhanping (author)The use of reclaimed asphalt pavement (RAP) is a hot research topic in the field of road engineering, as there are still many issues to overcome so as to become standard engineering applications. The diffusion of virgin/aged asphalt binder is a key process to improve RAP performance. In this study, the asphalt binder diffusion models were...journal article 2021
