Comparative analysis of time sweep testing evaluation methods for the fatigue characterisation of aged bitumen (2024)
Journal Article
Hu, Y., Sreeram, A., Airey, G., Li, B., Si, W., & Wang, H. (2024). Comparative analysis of time sweep testing evaluation methods for the fatigue characterisation of aged bitumen. Construction and Building Materials, 432, Article 136698. https://doi.org/10.1016/j.conbuildmat.2024.136698

Ageing of bitumen changes its stiffness related properties and is thought to have a considerable impact on its fatigue performance. Time sweep tests are a commonly used methodology to evaluate the fatigue performance of bitumen over the course of its...

Examining the efficacy of promising antioxidants to mitigate asphalt binder oxidation: insights from a worldwide interlaboratory investigation (2024)
Journal Article
Adwani, D., Pipintakos, G., Mirwald, J., Wang, Y., Hajj, R., Guo, M., …Bhasin, A. (2024). Examining the efficacy of promising antioxidants to mitigate asphalt binder oxidation: insights from a worldwide interlaboratory investigation. International Journal of Pavement Engineering, 25(1), Article 2332363. https://doi.org/10.1080/10298436.2024.2332363

Oxidative aging induces significant stiffening of asphalt binders that leads to a pronounced reduction in the overall durability of asphalt pavements. The strategic implementation of antioxidant additives provides a potential solution to alleviate th...

A molecular dynamics analysis of the influence of iron corrosion products on the healing process of bitumen (2024)
Journal Article
Xu, H., Zou, Y., Airey, G., Wang, H., Zhang, H., Wu, S., & Chen, A. (2024). A molecular dynamics analysis of the influence of iron corrosion products on the healing process of bitumen. Construction and Building Materials, 421, Article 135662. https://doi.org/10.1016/j.conbuildmat.2024.135662

Corrosion of iron materials in the asphalt concrete pavement occurs commonly when the bitumen film peels off, and the generation of corrosion products would affect the healing performance of bitumen. To identify the affection, this research focuses o... Read More about A molecular dynamics analysis of the influence of iron corrosion products on the healing process of bitumen.

Interfacial characteristics between bitumen and corrosion products on steel slag surface from molecular scale (2024)
Journal Article
Xu, H., Zou, Y., Airey, G., Wang, H., Zhang, H., Wu, S., …Liang, Y. (2024). Interfacial characteristics between bitumen and corrosion products on steel slag surface from molecular scale. Construction and Building Materials, 417, Article 135324. https://doi.org/10.1016/j.conbuildmat.2024.135324

Corrosion commonly happened on the surface of steel slag during the weathering and accumulation process, whose products would form weak points and affect the interface between bitumen and steel slag. To clear its characteristics in the atomic scales,... Read More about Interfacial characteristics between bitumen and corrosion products on steel slag surface from molecular scale.

Wetting of bio-rejuvenator nanodroplets on bitumen: A molecular dynamics investigation (2024)
Journal Article
