Journal Article
Zhou, L., Airey, G., Zhang, Y., & Wang, C. (2025). Decoupling oxidation and hardening in ageing: evaluation of bitumen-stone adhesion using different experimental methods. Road Materials and Pavement Design, 26(Sup 1), 734-750. https://doi.org/10.1080/14680629.2025.2486525

The adhesion at the bitumen-aggregate interface critically affects asphalt pavement resistance to moisture damage and cracking and is significantly influenced by the bitumen ageing process. Coupled oxidation and hardening during ageing lead to varyin...

Atomic force microscopy (AFM) based microstructural and micromechanical analysis of bitumen during ageing and rejuvenation (2025)
Journal Article
Hu, Y., Yin, Y., Sreeram, A., Si, W., Airey, G. D., Li, B., Singh, B., Özdemir, D. K., & Zhou, L. (2025). Atomic force microscopy (AFM) based microstructural and micromechanical analysis of bitumen during ageing and rejuvenation. Construction and Building Materials, 467, Article 140387. https://doi.org/10.1016/j.conbuildmat.2025.140387

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...

Enhancing fatigue resistance and low-temperature performance of asphalt pavements using antioxidant additives (2025)
Journal Article
Hu, Y., Cheng, X., Sreeram, A., Si, W., Li, B., Pipintakos, G., & Airey, G. D. (2025). Enhancing fatigue resistance and low-temperature performance of asphalt pavements using antioxidant additives. Materials and Structures, 58(1), Article 46. https://doi.org/10.1617/s11527-025-02574-4

Ageing results in significant performance deterioration of asphalt, especially in relation to its fatigue and low-temperature performance. This performance deterioration can theoretically be lowered by incorporating antioxidants in asphalt mixtures....
