A novel approach for rational determination of warm mix asphalt production temperatures (2018)
Journal Article
Abed, A., Thom, N., & Grenfell, J. (2019). A novel approach for rational determination of warm mix asphalt production temperatures. Construction and Building Materials, 200, 80-93. https://doi.org/10.1016/j.conbuildmat.2018.12.082

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...

Investigation into the bond strength of bitumen-fibre mastic (2018)
Journal Article
Mohammed, M., Parry, T., Thom, N., & Grenfell, J. (2018). Investigation into the bond strength of bitumen-fibre mastic. Construction and Building Materials, 190, 382-391. https://doi.org/10.1016/j.conbuildmat.2018.09.084

The loss of bond strength in road pavement surfacing due to high traffic loads or moisture is a recurring problem, creating distresses such as ravelling, fatigue and rutting. It is, therefore, important to find a way to prevent or at least delay the... Read More about Investigation into the bond strength of bitumen-fibre mastic.

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...

Use of bitumen-stabilised ballast for improving railway trackbed conventional maintenance (2018)
Journal Article
D'Angelo, G., Sol-Sánchez, M., Moreno-Navarro, F., Lo Presti, D., & Thom, N. (2018). Use of bitumen-stabilised ballast for improving railway trackbed conventional maintenance. Géotechnique, 68(6), 518-527. https://doi.org/10.1680/jgeot.17.P.022

Despite its many advantages, ballasted track needs frequent maintenance to ensure an adequate quality of service. However, tamping, traditionally used to correct geometry, causes ballast degradation and loosening of the already compacted ballast laye...

Recycled hybrid fiber-reinforced & cement-stabilized pavement mixtures: tensile properties and cracking characterization (2018)
Journal Article
Farhan, A. H., Dawson, A., & Thom, N. (2018). Recycled hybrid fiber-reinforced & cement-stabilized pavement mixtures: tensile properties and cracking characterization. Construction and Building Materials, 179, https://doi.org/10.1016/j.conbuildmat.2018.05.233

Cement-stabilized aggregate mixtures (CSAMs) have been used effectively within semi-rigid pavement structures. However, the sensitivity to cracking under tensile loading is the main problem that may cause a deterioration due to reflection to the over...

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, doi: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...

Damage propagation rate and mechanical properties of recycled steel fiber-reinforced and cement-bound granular materials used in pavement structure (2018)
Journal Article

Cement-bound granular mixtures (CBGMs) represent an attractive option to increase load-carrying capacity and sustainability in highway construction. However, reflection cracking of overlying pavement layers due to the low tensile strength of CBGMs re...

Linear viscous approach to predict rut depth in asphalt mixtures (2018)
Journal Article

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.
