Aging deteriorates the performance of bitumen whereas rejuvenation can partially restore these properties. Although the macroscale properties of bitumen ageing and rejuvenation have been well documented, the microscale mechanisms are still not well u...

A novel fatigue test method for bitumen-stone combinations under cyclic tension-compression loading (2024)
Journal Article
Zhou, L., Airey, G., Zhang, Y., Huang, W., & Wang, C. (2025). A novel fatigue test method for bitumen-stone combinations under cyclic tension-compression loading. Materials and Design, 249, Article 113577. https://doi.org/10.1016/j.matdes.2024.113577

Asphalt pavement distress is closely linked to the fatigue performance of asphalt mixtures. Traditional fatigue tests like the dynamic shear rheometer (DSR) cannot assess failure between bitumen and stone, while methods like the four-point bending (4...

Efficiency of Sustainable Rejuvenation of Bitumen Using Bio-based Rejuvenators and Waste Oils (2024)
Presentation / Conference Contribution
Hu, Y., Ryan, J., Allanson, M., Wang, H., Zhou, L., & Airey, G. (2024, June). Efficiency of Sustainable Rejuvenation of Bitumen Using Bio-based Rejuvenators and Waste Oils. Presented at 14th International Conference on Asphalt Pavements ISAP2024, Montreal, QC, Canada

This study primarily investigated the efficacy of sustainable rejuvenators in restoring the properties of aged bitumen as well as developing a method for optimising rejuvenator dosages. The rheological properties, determined via frequency sweep and l... Read More about Efficiency of Sustainable Rejuvenation of Bitumen Using Bio-based Rejuvenators and Waste Oils.
