Journal Article
Airey, G. D., Rowe, G. M., Sias, J. E., Di Benedetto, H., Sauzeat, C., & Dave, E. V. (2022). Black Space Rheological Assessment of Asphalt Material Behavior. Journal of Testing and Evaluation, 50(2), 770-787. https://doi.org/10.1520/JTE20210205

Black Space diagrams representing rheological data of asphalt materials in the form of complex modulus (|G*| or |E*|) versus phase angle (δ) have been successfully used for interpretation of material behavior and performance. Previous studies have us... Read More about Black Space Rheological Assessment of Asphalt Material Behavior.

Effect of hydrated lime and other mineral fillers on stiffening and oxidative ageing in bitumen mastic (2021)
Journal Article
Alfaqawi, R. M., Fareed, A., Zaidi, S. B. A., Airey, G. D., & Rahim, A. (2022). Effect of hydrated lime and other mineral fillers on stiffening and oxidative ageing in bitumen mastic. Construction and Building Materials, 315, Article 125789. https://doi.org/10.1016/j.conbuildmat.2021.125789

The bituminous binder's ageing process is the primary reason behind the decrement in the pavement's in-service life, which can lead to cracking as a result of extreme hardening of the binder. In order to mitigate this problem, several methods have be... Read More about Effect of hydrated lime and other mineral fillers on stiffening and oxidative ageing in bitumen mastic.

Crack Self-healing in Asphalt as a Flow Process (2021)
Book Chapter
Grossegger, D., Garcia, A., & Airey, G. (2022). Crack Self-healing in Asphalt as a Flow Process. In Proceedings of the RILEM International Symposium on Bituminous Materials (489-495). Springer International Publishing. https://doi.org/10.1007/978-3-030-46455-4_62

Asphalt has the ability to restore diminished properties caused by damage. This ability is known as self-healing and in case of asphalt it is conferred upon by the competent bitumen. Bitumen is a viscoelastic liquid and has self-healing abilities due... Read More about Crack Self-healing in Asphalt as a Flow Process.

Modelling the stiffness development in asphalt concrete to obtain fatigue failure criteria (2021)
Journal Article
Chen, A., Airey, G. D., Thom, N., Litherland, J., & Adjetey Nii-Adjei, R. (2021). Modelling the stiffness development in asphalt concrete to obtain fatigue failure criteria. Construction and Building Materials, 306, Article 124837. https://doi.org/10.1016/j.conbuildmat.2021.124837

The study of fatigue is critical to good usability and durability of asphalt pavements. Inaccurate calculation of the fatigue failure criteria can cause incorrect evaluation of the fatigue performance, leading to inaccurate prediction of the pavement...

Stiffening Effect of Fillers Based on Rheology and Micromechanics Models (2021)
Journal Article
Rahim, A., Milad, A., Yusoff, N. I. M., Airey, G., & Thom, N. (2021). Stiffening Effect of Fillers Based on Rheology and Micromechanics Models. Applied Sciences, 11(14), Article 6521. https://doi.org/10.3390/app11146521

The aggregate in an asphalt mixture is coated with mastic consisting of bitumen (dilute phase) and filler (particulates phase). The interaction of bitumen and filler and packing of filler plays an important role in the properties of mastics. The micr...

Rheological characterisation of cold bitumen emulsion slurries (2021)
Journal Article
Mignini, C., Lo Presti, D., Airey, G., & Graziani, A. (2021). Rheological characterisation of cold bitumen emulsion slurries. Road Materials and Pavement Design, 22(Sup1), S232-S250. https://doi.org/10.1080/14680629.2021.1906303

The performance of cold bitumen emulsion (CBE) mixtures is strongly linked to an optimised design of the binder blends and mastics. Types and dosages of bitumen, mineral additions and the workability must be characterised and optimised. This study ai...
