Journal Article
Nassar, A. I., Thom, N., & Parry, T. (2016). Optimizing the mix design of cold bitumen emulsion mixtures using response surface methodology. Construction and Building Materials, 104, https://doi.org/10.1016/j.conbuildmat.2015.12.073

Cold mix asphalt (CMA) has been increasingly recognized as an important alternative worldwide. One of the common types of CMA is cold bitumen emulsion mixture (CBEM). In the present study, the optimization of CBEM has been investigated, to determine... Read More about Optimizing the mix design of cold bitumen emulsion mixtures using response surface methodology.

Effect of aggregate gradation on the stiffness of asphalt mixtures (2015)
Journal Article
Al-Mosawe, H., Thom, N., Airey, G., & Ai-Bayati, A. (2015). Effect of aggregate gradation on the stiffness of asphalt mixtures. International Journal of Pavement Engineering and Asphalt Technology, 16(2), https://doi.org/10.1515/ijpeat-2015-0008

Aggregate gradation plays an important role in the behaviour of asphalt mixtures. Packing of aggregate is a very important factor that will be affected by changing the aggregate gradation. Many researchers have investigated different ways of describi... Read More about Effect of aggregate gradation on the stiffness of asphalt mixtures.

The use of additives to enhance properties of pre-formed foamed concrete (2015)
Journal Article
Hilal, A. A., Thom, N., & Dawson, A. (2015). The use of additives to enhance properties of pre-formed foamed concrete. International Journal of Engineering and Technology, 7(4), https://doi.org/10.7763/IJET.2015.V7.806

This paper describes an experimental study of an enhancement of pre-formed foamed concrete, 1300-1900 kg/m3, by utilising two types of additives, silica fume and fly ash, to partially replace Portland cement and fine sand. It focuses on consistency,... Read More about The use of additives to enhance properties of pre-formed foamed concrete.

Improvement of the service life of sustainable self-compacting concrete SCC by integrating high dosage of cement replacement (2015)
Journal Article
Mohammed, K. M., Dawson, A., & Thom, N. (2015). Improvement of the service life of sustainable self-compacting concrete SCC by integrating high dosage of cement replacement

Based on simple diffusion theory and a timedependent factor (?) for the chloride diffusion coefficient, chloride penetration through concrete was numerically modelled and the service life was predicted. This was done for two reference mixes (normal v... Read More about Improvement of the service life of sustainable self-compacting concrete SCC by integrating high dosage of cement replacement.

On void structure and strength of foamed concrete made without/with additives (2015)
Journal Article
Hilal, A. A., Thom, N., & Dawson, A. (2015). On void structure and strength of foamed concrete made without/with additives. Construction and Building Materials, 85, https://doi.org/10.1016/j.conbuildmat.2015.03.093

A study has been undertaken to investigate the effect of different additives on the strength foamed concrete by characterising air-void size and shape parameters and identifying the influence of these parameters and changes to cement paste microstruc...

Stiffness of cold asphalt mixtures with recycled aggregates from construction and demolition waste (2015)
Journal Article
Gómez-Meijide, B., Pérez, I., Airey, G., & Thom, N. (2015). Stiffness of cold asphalt mixtures with recycled aggregates from construction and demolition waste. Construction and Building Materials, 77, 168-178. https://doi.org/10.1016/j.conbuildmat.2014.12.045

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...
