Characterisation of bitumen through multiple ageing-rejuvenation cycles (2024)
Journal Article
Hu, Y., Allanson, M., Sreeram, A., Ryan, J., Wang, H., Zhou, L., …Airey, G. D. (2024). Characterisation of bitumen through multiple ageing-rejuvenation cycles. International Journal of Pavement Engineering, 25(1), Article 2365350. https://doi.org/10.1080/10298436.2024.2365350

The multiple recycling of bitumen offers the possibility of reusing it for repeated lifecycles and achieve a higher degree of circularity of materials used in pavement construction. Aiming to identify the prospect, this study aged bitumen in a labora... Read More about Characterisation of bitumen through multiple ageing-rejuvenation cycles.

Use of Hansen Solubility Parameters (HSP) in the selection of highly effective rejuvenators for aged bitumen (2024)
Journal Article
Hu, Y., Sreeram, A., Xia, W., Wang, H., Zhou, L., Si, W., & Airey, G. D. (2024). Use of Hansen Solubility Parameters (HSP) in the selection of highly effective rejuvenators for aged bitumen. Road Materials and Pavement Design, https://doi.org/10.1080/14680629.2024.2357684

While there is considerable research regarding the recycling and reuse of aged bitumen in terms of the evaluation of rheological properties, there is not much fundamental understanding regarding the underlying mechanisms of the rejuvenation process....

Investigation of the bonding properties of bitumen using a novel modified binder bond strength test (2024)
Journal Article
Zhou, L., Airey, G., Zhang, Y., Wang, C., & Zhong, H. (2024). Investigation of the bonding properties of bitumen using a novel modified binder bond strength test. Construction and Building Materials, 434, Article 136784. https://doi.org/10.1016/j.conbuildmat.2024.136784

The binder bond strength (BBS) test can directly quantify the bonding of bitumen-stone joints. However, the index "bond strength" used in this method cannot provide a clear distinction when evaluating the performance of various bitumen, and some resu...

Optimising the dosage of bio-rejuvenators in asphalt recycling: A rejuvenation index based approach (2024)
Journal Article
Hu, Y., Ryan, J., Sreeram, A., Allanson, M., Pasandín, A. R., Zhou, L., …Airey, G. D. (2024). Optimising the dosage of bio-rejuvenators in asphalt recycling: A rejuvenation index based approach. Construction and Building Materials, 433, Article 136761. https://doi.org/10.1016/j.conbuildmat.2024.136761

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.

Critical considerations and effective assessment of extraction and recovery processes of RAP (2023)
Journal Article
Zhong, H., Huang, W., Lin, P., Zhou, L., & Lv, Q. (2023). Critical considerations and effective assessment of extraction and recovery processes of RAP. Construction and Building Materials, 403, Article 133039. https://doi.org/10.1016/j.conbuildmat.2023.133039

With the increasing shortage of resources, the reuse of recycled asphalt pavements (RAP) in pavement engineering is considered as a sustainable technology. Challenges posed by common extraction and recovery methods may result in misjudgment of asphal...

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.
