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....

Physicochemical compatibility assessment of bio-additives and bitumen using solubility science-based approaches (2025)
Journal Article
Hu, Y., Sreeram, A., Al-Tabbaa, A., & Airey, G. D. (2025). Physicochemical compatibility assessment of bio-additives and bitumen using solubility science-based approaches. Fuel, 387, Article 134361. https://doi.org/10.1016/j.fuel.2025.134361

Increasing environmental concerns necessitate the urgent investigation of alternative, sustainable resources as replacement for fossil fuel-derived bitumen; the primary material used for road construction. One of the promising approaches is the use o... Read More about Physicochemical compatibility assessment of bio-additives and bitumen using solubility science-based approaches.

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.
