While significant research efforts have been devoted to the rejuvenation of aged bitumen using bio-rejuvenators, a universally recognised approach for dosage optimisation is still yet to be established. Aiming to develop standardised methods to deter... Read More about Optimising the dosage of bio-rejuvenators in asphalt recycling: A rejuvenation index based approach.

Evaluating the ageing degrees of bitumen by rheological and chemical indices (2023)
Journal Article
Hu, Y., Xia, W., Xue, Y., Zhao, P., Wen, X., Si, W., …Airey, G. D. (2023). Evaluating the ageing degrees of bitumen by rheological and chemical indices. Road Materials and Pavement Design, 24(sup1), 19-36. https://doi.org/10.1080/14680629.2023.2180289

The ageing of bitumen is an inevitable phenomenon which is still challenging to be characterised. This paper aims at evaluating the ageing degrees of bitumen comprehensively. There were six types of bitumen being aged to five levels for comparing pur... Read More about Evaluating the ageing degrees of bitumen by rheological and chemical indices.
