Delivering Resilient Roads: The Reality of Bitumen Stabilisation for Granular Base Materials

Bitumen (foamed bitumen and bitumen emulsion) stabilisation has been successfully deployed across some of Australia's most flood-prone road networks, helping road agencies improve resilience, reduce maintenance demands, and minimise disruption to communities.

Join us for this NTRO Edge Online session as we explore how this proven technology is being applied in practice and the benefits it is delivering across the transport sector.

Dr Didier Bodin, from the National Transport Research Organisation (NTRO), will provide an overview of bitumen stabilisation, explaining the science behind the technology, where it is most effective, and the conditions that make it a successful resilience treatment.

We will then hear from Damien Volker of the Queensland Department of Transport and Main Roads (TMR), who will share the department's experience implementing bitumen stabilisation across its network. The presentation will cover the impact on maintenance and operational programs, budget outcomes, and the development of supporting specifications that have enabled broader deployment.

Finally, Allen Browne from HIWAY will provide an industry perspective, discussing the practical journey from early adoption to routine delivery. Allen will share insights into equipment commissioning, workforce capability development, construction practices, and the lessons learned in successfully integrating the technology into day-to-day operations.

Why Attend?

Gain Practical Insights: How bitumen stabilisation is being successfully applied across Australia's road networks to improve pavement performance and resilience.

Real-World Case Studies: Hear directly from transport agency and industry leaders about the challenges, successes, and lessons learned from network-scale implementation

Strategies to Reduce Potholes and Maintenance Demand: Understand how stabilised pavements can reduce recurring defects, lower maintenance requirements, and improve whole-of-life asset performance

Better Asset Management Outcomes: Discover how transport agencies are using this technology to extend pavement life, optimise maintenance budgets, and improve service levels for communities

Technical Knowledge You Can Apply: Gain a deeper understanding of the science, design considerations, specifications, construction practices, and operational requirements that underpin successful projects.

Future-Focused Resilience Planning: Explore how bitumen stabilisation can support climate adaptation objectives and help road owners build more resilient transport networks capable of withstanding increasingly challenging operating conditions.

Whether you are responsible for designing, delivering, maintaining, or managing road infrastructure, this session will provide valuable evidence, practical experience, and actionable insights to help improve the resilience and performance of your network.
