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.

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...
