Construction Sciences Foamed Bitumen Supervisor and Engineer Theja Rathnayake recently delivered a presentation on the role of laboratory testing and technical expertise in supporting stabilisation design and verification. Her presentation outlined how engineering support provided by quality testing of foamed bitumen and trial mixes contributes to reliable pavement performance and project outcomes.
The inaugural South East Queensland Pavement Stabilised Workshop hosted by Stabilised Pavements of Australia (SPA) was supported by Construction Sciences and the Foamed Bitumen team from our Brisbane South – Kingston laboratory. The workshop brought together more than 35 industry participants, including representatives from local councils across South East Queensland, as well as consultants and pavement specialists. The event focused on practical experiences and lessons learned from implementing in-situ pavement stabilisation and recycling in urban environments.
Guest speakers from organisations included Ipswich City Council, Redland City Council, Sunshine Coast Council, Transport and Main Roads, GenEng and a consultant from Sydney shared their experiences and journeys of using insitu stabilisation in urban environments over many years/decades, with presentations highlighting the long-term performance, sustainability and cost benefits of pavement recycling techniques used in road networks.
As the session sponsor, our team had the opportunity to contribute to industry discussions on mix design verification, performance testing, and the increasing adoption of FBS across road rehabilitation projects. Theja’s presentation highlighted the importance of independent resilient modulus testing, batch validation and compliance with TMR and Austroads methodologies. Many of the attendees are already working with Construction Sciences and designers from SPA on foamed bitumen stabilisation projects across the state.
Construction Sciences is proud to support successful workshop events for industry professionals to exchange knowledge and explore practical approaches to sustainable pavement construction and rehabilitation. Construction Sciences continues to advance pavement recycling and stabilisation practices through testing expertise, technical collaboration, and industry engagement.
