Ren, S. (author), Liu, X. (author), Varveri, Aikaterini (author), Khalighi, S. (author), Jing, R. (author), Erkens, S. (author)The rejuvenation efficiency of aged bitumen is the main concern when developing rejuvenating agents. It is necessary to develop a method to assess the efficiency of rejuvenators using rheological parameters in the whole frequency region. To this end, the 2S2P1D micromechanics model is adopted to fit the entire G∗ master curves of various...journal article 2023

Ren, S. (author), Liu, X. (author), van Aggelen, M. (author), Lin, P. (author), Erkens, S. (author)This study investigates the impacts of rejuvenator type/dosage and the aging degree of bitumen on the chemical and rheological properties of rejuvenated bitumen, and propose critical chemo-rheological indicators for evaluating rejuvenation efficiency. Moreover, the potential connections between essential chemical and rheological indices of...journal article 2023
