The composition of the material phase responsible for the self-healing of macro-cracks in asphalt mortar beams (2020)
Journal Article
Grossegger, D., Garcia, A., & Airey, G. (2022). The composition of the material phase responsible for the self-healing of macro-cracks in asphalt mortar beams. Road Materials and Pavement Design, 23(3), 656-665. https://doi.org/10.1080/14680629.2020.1842793

Self-healing of asphalt is assumed to be a flow process where bitumen flows into cracks to close them. Hence, the rheological behaviour of bitumen is one of the main factors affecting self-healing together with damage history, healing duration and pr...

Air voids play an important role in the temperature evolution of asphalt pavements exposed to the sun's radiation and the environment, but their effects have never been precisely quantified before. The objective of this article is to understand and q... Read More about Thermal properties of asphalt pavements under dry and wet conditions.

Multivariable analysis of potential evaporation from moist asphalt mixture (2015)
Journal Article
Garcia, A., Hassn, A., Chiarelli, A., & Dawson, A. (2015). Multivariable analysis of potential evaporation from moist asphalt mixture. Construction and Building Materials, 98, https://doi.org/10.1016/j.conbuildmat.2015.08.061

Asphalt pavements are normally dark colored and may get a very high temperature difference with the environment during daytime, but the influence of water evaporation in their temperature is unknown. Water evaporation experiments have been conducted... Read More about Multivariable analysis of potential evaporation from moist asphalt mixture.

Parametric analysis of energy harvesting pavements operated by air convection (2015)
