James leads the recycled and alternative materials stream within the Sustainability and Resilience team.
He is currently working on several projects related to the utilisation of waste resources in road infrastructure. These are focused on glass in asphalt and in granular sublayers. He also has plenty of experience looking at reclaimed asphalt pavement, crumb rubber modified asphalt and warm mix asphalt technologies.
Since joining ARRB James’ work has been focused on improving knowledge on foamed bitumen stabilised pavements and the use of lightly cemented materials in pavement construction.
He has also conducted new research on the addition of nanosilica to asphalt to improve properties and the addition of recycled crushed glass to asphalt to help reduce waste stockpiles.
James has a PhD in Metallurgy and Materials from the University of Birmingham in the UK.
James worked for 13 years as a researcher at the Nottingham Transportation Engineering Centre at the University of Nottingham in the UK. During this time, he worked on and managed projects involving the permanent deformation and fatigue properties of asphaltic materials, moisture damage in asphalt pavements, adhesion of bitumen to aggregate, warm mix asphalt technologies, the use of crumb rubber and recycled asphalt and alternative binders.
His main research interests are the fundamentals of adhesion, moisture damage of asphaltic materials, recycling and the use of secondary materials.
He has published more than 100 journal papers and peer reviewed conference papers. He is a Director-at-large of the International Society of Asphalt Pavements, on the Editorial board for the Proceedings of the Association of Asphalt Paving Technologists and involved in several RILEM Technical Committees looking at bituminous and asphaltic materials.
