Experimental evaluation of cohesive and adhesive bond strength and fracture energy of bitumen-aggregate systems (2015)
Journal Article
Zhang, J., Airey, G. D., & Grenfell, J. R. (2016). Experimental evaluation of cohesive and adhesive bond strength and fracture energy of bitumen-aggregate systems. Materials and Structures, 49(7), 2653-2667. https://doi.org/10.1617/s11527-015-0674-7

Degradation of asphalt pavements is an inevitable phenomenon due to the combined effects of high traffic loads and harsh environmental conditions. Deterioration can be in the form of cohesive failure of the bitumen and/or bitumen-filler mastic or by...

Influence of aggregate mineralogical composition on water resistance of aggregate–bitumen adhesion (2015)
Journal Article
Zhang, J., Apeagyei, A. K., Airey, G. D., & Grenfell, J. R. (2015). Influence of aggregate mineralogical composition on water resistance of aggregate–bitumen adhesion. International Journal of Adhesion and Adhesives, 62, https://doi.org/10.1016/j.ijadhadh.2015.06.012

The effects of aggregate mineralogical composition on moistures sensitivity of aggregate–bitumen bonds were investigated using four aggregate types (two limestone and two granite)and two bitumen grades (40/60 penand70/100pen). Moisture sensitivity... Read More about Influence of aggregate mineralogical composition on water resistance of aggregate–bitumen adhesion.

Discrete element modelling of creep of asphalt mixtures (2015)
Journal Article
Cai, W., McDowell, G. R., Airey, G., & de Bono, J. P. (in press). Discrete element modelling of creep of asphalt mixtures. Geomechanics and Geoengineering, 11(1), https://doi.org/10.1080/17486025.2015.1006689

Creep tests on asphalt mixtures have been undertaken under four stress levels in the laboratory while the Discrete Element Model (DEM) has been used to simulate the laboratory tests. A modified Burger’s model has been used to represent the time-depen... Read More about Discrete element modelling of creep of asphalt mixtures.

Stiffness of cold asphalt mixtures with recycled aggregates from construction and demolition waste (2015)
Journal Article

The stiffness of cold asphalt mixtures (CAM) with 100% recycled construction and demolition waste aggregates (CDWA) was studied from three different points of view: the indirect tensile stiffness modulus (ITSM), the dynamic modulus at different tempe...
