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.

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.

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.
