SAMI bitumen at AfPA 2024: pavement life and whole-of-life costs for road engineers
Reviewed by Joe Ashwell
First reported on Roads & Infrastructure (AU)
30 Second Briefing
SAMI Bitumen Technologies used the 20th AfPA International Flexible Pavement Conference in Adelaide to showcase polymer-modified binders and spray seal technologies aimed at longer-life, lower-maintenance pavements. Under the “Driving Innovation and Sustaining the Planet” theme, the company focused on flexible pavement solutions tailored to Australian conditions, including high-temperature rut resistance and improved fatigue performance. For asset owners and contractors, the message centres on extending resurfacing intervals and reducing whole-of-life costs on heavily trafficked road corridors.
Technical Brief
- SAMI’s booth centred on polymer-modified binders and sprayed seals engineered for Australian flexible pavement networks.
- Product focus included high-performance binders for sprayed sealing as well as asphalt surfacing applications.
- Delegates were targeted across asset owner, designer and contractor groups for network-level pavement performance discussions.
- Technical messaging emphasised tailoring binder rheology to local climate, traffic loading and construction practices.
- SAMI used the AfPA platform to position its technologies within emerging “future-ready roads” specifications.
Our Take
Within the 418 Infrastructure stories in our database, only a small subset tagged both ‘Product’ and ‘Sustainability’ focus on pavement materials, so SAMI Bitumen Technologies’ presence at the 20th AfPA International Flexible Pavement Conference positions it among a relatively select group pushing lower‑impact surfacing solutions in Australia.
AfPA’s Adelaide Convention Centre conference has become a key forum in our coverage for translating sustainability policy into product specifications, meaning SAMI’s messaging here is likely to influence how Australian road authorities and contractors frame future performance and emissions requirements for flexible pavements.
Across the 1143 tag‑matched pieces, most sustainability‑labelled infrastructure items are about energy or structures rather than pavements, suggesting bitumen and asphalt suppliers like SAMI still have room to shape the agenda on lifecycle carbon, recycled content and durability metrics before standards fully crystallise.
