Journal Article
Grenfell, J., Ahmad, N., Liu, Y., Apeagyei, A. K., Large, D., & Airey, G. (2014). Assessing asphalt mixture moisture susceptibility through intrinsic adhesion, bitumen stripping and mechanical damage. Road Materials and Pavement Design, 15(1), 131-152. https://doi.org/10.1080/14680629.2013.863162

Durability is one of the most important properties of an asphalt mixture. A key factor affecting the durability of asphalt pavements is moisture damage. Moisture damage is generally considered to be the result of two main mechanisms; the loss of adhe...

Tyre rubber-modified bitumens development: the effect of varying processing conditions (2013)
Journal Article
Lo Presti, D., & Airey, G. (2013). Tyre rubber-modified bitumens development: the effect of varying processing conditions. Road Materials and Pavement Design, 14(4), 888-900. doi:10.1080/14680629.2013.837837

Tyre rubber-modified binders (TR-MBs), produced through McDonald's wet process and used worldwide (e.g. asphalt rubber), have been demonstrated to provide various benefits to pavements and, moreover, they represent a good opportunity for recycling ty...

The role of ettringite in the deterioration of artificial lime stabilised soils: a microstructural study (2013)
Journal Article
Buttress, A., Grenfell, J., & Airey, G. (2013). The role of ettringite in the deterioration of artificial lime stabilised soils: a microstructural study. Road Materials and Pavement Design, 14(3), https://doi.org/10.1080/14680629.2013.779306

The formation of ettringite has been defined as a major failure mechanism of lime stabilised cohesive soils. It can result in both disruptive volumetric changes and loss of mechanical strength. The mechanisms of its formation and the role it plays in... Read More about The role of ettringite in the deterioration of artificial lime stabilised soils: a microstructural study.

Evaluation of moisture sorption and diffusion characteristics of asphalt mastics using manual and automated gravimetric sorption techniques (2013)
Journal Article
Apeagyei, A. K., Grenfell, J., & Airey, G. (2014). Evaluation of moisture sorption and diffusion characteristics of asphalt mastics using manual and automated gravimetric sorption techniques. Journal of Materials in Civil Engineering, 26(8), Article 04014045. https://doi.org/10.1061/%28ASCE%29MT.1943-5533.0000929

One of the most important factors influencing the durability of asphalt mixtures is moisture-induced damage resulting from the presence and the transport of moisture in pavements. Moisture-induced damage is an extremely complicated phenomenon that is...
