Re-development of Tata Steel’s successful Vetex® highways restraint system will deliver multiple benefits to system installers and road operators.
Accepted by Highways England, the latest Vetex® normal containment (N2) system replaces multiple post and barrier beam designs with standardised, interchangeable components. Combined with wider post centres – allowing a significant reduction in the number of installed system components – the improved and simplified system offers one beam and one post type across all working widths. The result is a system that is:
- lighter
- quicker to install
- easier to maintain
Re-development has also extended Vetex® N2 capability to include a W1 working width solution. Lower working width systems save space and offer scope for extra running lanes on highways.
In addition, system versatility has been enhanced with dual certification of Vetex® N2 W1 single-sided barrier as H1 W3. Vetex® N2 W4 single-sided barrier has also been dual certified as N1 W2.
Rigorous development process
Suitable for both single-sided and double-sided application, the new Vetex® N2 system marks the culmination of a three-year design and development programme.
A rigorous design and development process included extensive performance modelling followed by comprehensive, independent testing of the new Vetex® N2 system.
“Post dimensions were carefully designed to optimise post performance at wider post centres,” said Trevor. “Vetex® N2 now has a single, rectangular hollow section post which can withstand higher loads and reduce system deflection. The new post profile reduces system width and is also more pedestrian-friendly.”
Next steps for Vetex® include re-development and simplification of higher containment systems to deliver similar benefits.
