    SAMI new technical centre: binder performance and testing insights for road engineers

    SAMI new technical centre: binder performance and testing insights for road engineers

    First reported on Roads & Infrastructure (AU)

    30 Second Briefing

    SAMI Bitumen Technologies has opened a new technical centre to expand research and development of bitumen additives and performance enhancers for Australian road construction and maintenance. The facility centralises laboratory testing, product formulation and quality control for polymer-modified binders, emulsions and warm-mix technologies, improving collaboration between SAMI’s technical teams and its large-scale production network. For pavement designers and asset owners, the centre signals faster validation of high-performance binders and more consistent field performance data for heavily trafficked highways and sprayed-seal networks.

    Technical Brief

    • Outputs are intended for direct application in mix design optimisation, seal design selection and surfacing maintenance strategies.

    Our Take

    SAMI Bitumen Technologies’ new technical centre in Australia sits alongside COLAS’s ‘One COLAS Bitumen’ framework rollout (Nov 2025), suggesting the lab is likely to be a regional node for standardised binder and emulsion development rather than a standalone R&D outpost.

    At the AfPA International Flexible Pavement Conference in Adelaide (Jan 2026), SAMI highlighted polymer-modified binders and spray seals, so this centre will probably be geared to performance testing and local adaptation of those systems to Australian climate and traffic conditions.

    Within the 41 Materials stories in our database, SAMI is one of the few bitumen-focused operators with both a dedicated technical centre and a global parent (COLAS), which tends to give road authorities and contractors more confidence around long-term product support and specification stability.

    UK Concrete Show 2026 seminar line-up: decarbonisation and QA/QC focus for engineers

    The UK Concrete Show 2026 at Birmingham’s NEC on 25–26 March will run a seminar programme centred on decarbonisation, materials innovation, digital monitoring, performance verification, and skills development for concrete producers and specifiers. Sessions will address low‑carbon binders and mix designs, sensor‑based monitoring of pours and in‑service structures, and verification of performance against evolving standards. The focus on skills suggests practical content for contractors, precast manufacturers, and designers needing to integrate new materials and digital QA/QC into existing workflows.

    Tobermore £160k fatality fine: lockout and interlock lessons for plant engineers

    Precast manufacturer Tobermore Concrete Products has been fined £160,000 at Londonderry Crown Court after production team leader Colin Thomas was fatally crushed on 26 April 2023 at the HESS1 block manufacturing line at its Lisnamuck Road plant. Thomas entered a fenced pit area for cleaning when a horizontal latch conveyor restarted, trapping him between the moving conveyor and fixed structure because the line had not been fully isolated and locked out. HSENI found unclear interlock zoning, absence of safety light sensors on HESS1 despite their use on similar lines, and inadequate supervision of cleaning and maintenance practices.

    Shape memory alloy and UHPFRC for ageing bridges: design notes for engineers

    Swiss researchers have strengthened ageing bridge decks by embedding heat‑activated iron‑based shape memory alloy (Fe‑SMA) bars within an ultra‑high‑performance fibre‑reinforced concrete (UHPFRC) overlay, creating active prestress when the bars are heated. The Fe‑SMA bars contract on activation and lock in compressive stresses as the UHPFRC hardens, improving fatigue performance and crack control without adding significant self‑weight. This approach offers a thin, bonded strengthening layer that can be installed on existing decks with minimal clearance loss and limited traffic disruption.
