Warm Mix Asphalt (WMA) has been developed to minimise environmental impact of asphalt by reducing production temperatures of this material. This study provides a new approach to design WMA production temperatures by two methods. First, aggregate coat...

Design considerations of high RAP-content asphalt produced at reduced temperatures (2018)
Journal Article
Abed, A., Thom, N., & Lo Presti, D. (2018). Design considerations of high RAP-content asphalt produced at reduced temperatures. Materials and Structures, 51(4), Article 91. https://doi.org/10.1617/s11527-018-1220-1

In many countries recycling of reclaimed asphalt pavement (RAP) for road surface layers is limited to a maximum of 10–30%. This is due to technical limitation of common asphalt plant but also to specifications that are still restrictive when it comes...

Numerical and experimental predictions of texture-related influences on rolling resistance (2018)
Journal Article
Mansura, D. A., Thom, N. H., & Beckedahl, H. J. (2018). Numerical and experimental predictions of texture-related influences on rolling resistance. Transportation Research Record, https://doi.org/10.1177/0361198118776114

To overcome rolling resistance (RR) a typical vehicle on average consumes 4152 MJ/119 L of fuel annually as a result of both vehicle and pavement factors. A slight improvement in surface texture arrangement may therefore decrease fuel consumption b...

Developing the multiple stress–strain creep recovery (MS-SCR) test (2018)
Journal Article
Elnasri, M. M. H., Airey, G., & Thom, N. (in press). Developing the multiple stress–strain creep recovery (MS-SCR) test. Mechanics of Time-Dependent Materials, https://doi.org/10.1007/s11043-018-9387-y

While most published work from Europe has been concerned with evaluating binders’ resistance to rutting based on their stiffness (deformation resistance), work originating in the US has mainly been concerned with ranking binders based on their recove...

Linear viscous approach to predict rut depth in asphalt mixtures (2018)
Journal Article
Al-Mosawe, H., Thom, N., Airey, G., & Albayati, A. (in press). Linear viscous approach to predict rut depth in asphalt mixtures. Construction and Building Materials, 169, https://doi.org/10.1016/j.conbuildmat.2017.11.065

Rutting in asphalt mixtures is a very common type of distress. It occurs due to the heavy load applied and slow movement of traffic. Rutting needs to be predicted to avoid major deformation to the pavement. A simple linear viscous method is used i... Read More about Linear viscous approach to predict rut depth in asphalt mixtures.
