This year marked a major milestone for AustStab, as the Association celebrated 30 years at the forefront of pavement recycling and stabilisation. AustStab’s 2025 Conference in Adelaide showcased international expertise, local innovation and the maturing sophistication of a sector that is reshaping the delivery of sustainable and resilient road infrastructure.
The AustStab Annual Conference 2025, hosted from 11-13 August at Adelaide Oval, was more than a technical gathering; it was a celebration of an industry coming of age. Delegates heard from experts across Australia and around the world, with international speakers from South Africa, Brazil, New Zealand and the United Kingdom sharing proven practices and highlighting innovations that could inform Australian infrastructure delivery.
Technical presentations reinforced the tangible benefits of in-situ stabilisation, with case studies showing how costs and carbon footprints can be reduced without sacrificing durability. Sustainability was a central theme throughout the program, as speakers explored the need to embed carbon footprint measurement in treatment selection frameworks to ensure projects deliver long-term value, not just short-term savings.
A program with depth
The three-day event carried the theme Recycling the Road Ahead – Resilient | Sustainable | Cost-Effective. A highlight was the international panel moderated by NTRO CEO Michael Caltabiano, which brought together global experts to discuss how lessons from abroad could be adapted locally. Delegates also participated in a half-day workshop co-facilitated with the Department for Infrastructure and Transport South Australia (DIT SA), which centred on specification harmonisation and sustainability leadership.
The conference also provided a launchpad for new AustStab technical resources and training programs, ensuring the next generation of practitioners have the knowledge and tools to deliver high-quality stabilisation works across Australia.
Celebrating industry excellence
The Gala Dinner and Awards of Excellence was a fitting celebration of the sector’s achievements. Awards recognised innovation in safety, sustainability, and technical excellence.
Work Health & Safety: TMR – RoadTek North Queensland was honoured for its stabiliser drum stand improving worker safety.
Excellence in Consulting, Research or Education: The AustStab Technical Working Group received recognition for its work optimising slag/lime binders.
Sustainability & Innovation: SPA and Frankston City Council were awarded for their leadership in sustainable in-situ recycling solutions.
These winners reflect the collaborative spirit of AustStab, industry, government and researchers working together to raise standards, share knowledge and deliver better roads.
The atmosphere was electric as the industry celebrated not only its technical expertise but also its growing sophistication.

Building community beyond the podium
The conference experience extended beyond the lecture theatre. Delegates connected at the pre-conference golf day and welcome drinks, while the gala dinner provided a vibrant atmosphere to celebrate achievements. Attendees repeatedly emphasised the value of these informal moments, the conversations, introductions and connections that help sustain collaboration long after the conference ends.
Looking to the future
As AustStab enters its fourth decade, the success of the 2025 Conference reaffirmed its central role as a driver of sustainable, resilient and cost-effective road infrastructure. With international insights, national collaboration and a clear sustainability agenda, the Association has demonstrated that pavement recycling and stabilisation are no longer alternatives, they are the cornerstone of a smarter, greener road network for Australia.
