Novel performance-based technique for predicting maintenance strategy of bitumen stabilised ballast (2017)
Journal Article
D'Angelo, G., Bressi, S., Giunta, M., Lo Presti, D., & Thom, N. (2018). Novel performance-based technique for predicting maintenance strategy of bitumen stabilised ballast. Construction and Building Materials, 161, 1-8. doi:10.1016/j.conbuildmat.2017.11.115

Despite being the most used worldwide, railway ballasted tracks presents high maintenance cost related to ballast settlement and particle degradation. With the aim of reducing life cycle costs, bitumen stabilised ballast (BSB) has been recently propo...

Microstructural characteristics, porosity and strength development in ceramic-laterized concrete (2017)
Journal Article
Awoyera, P., Akinmusuru, J., Dawson, A., Ndambuki, J., & Thom, N. (2018). Microstructural characteristics, porosity and strength development in ceramic-laterized concrete. Cement and Concrete Composites, 86, https://doi.org/10.1016/j.cemconcomp.2017.11.017

Interfacial bonding between constituent materials and pore sizes in a concrete matrix are major contributors to enhancing the strength of concrete. In a bid to examine how this phenomenon affects a laterized concrete, this study explored the relation...

Structural design of pavements incorporating foamed bitumen mixtures (2017)
Journal Article
Kuna, K., Airey, G., & Thom, N. (in press). Structural design of pavements incorporating foamed bitumen mixtures. Proceedings of the ICE - Construction Materials, https://doi.org/10.1680/jcoma.16.00039

This paper presents a rational structural design methodology termed the ‘cumulative damage approach’ for road, port and airport pavements incorporating cold bituminous mixtures with foamed bitumen. This has been developed along with a laboratory test... Read More about Structural design of pavements incorporating foamed bitumen mixtures.

A novel multi-scale numerical model for prediction of texture-related impacts on fuel consumption (2017)
Journal Article
Mansura, D., Thom, N., & Beckedahl, H. (2017). A novel multi-scale numerical model for prediction of texture-related impacts on fuel consumption. Tire Science and Technology, 45(1), https://doi.org/10.2346/tire.17.450104

It is estimated that to overcome rolling resistance (RR) a typical vehicle, on average, consumes 4152 MJ/119 L of fuel annually, depending not only on vehicle-related factors but also on pavement-related factors. A slight improvement in surface prope... Read More about A novel multi-scale numerical model for prediction of texture-related impacts on fuel consumption.
