Testing
The Ironman Hybrid Barrier has been successfully crash tested to MASH 2016 Test Level 2 (TL-2) as a redirecting
longitudinal safety barrier for vehicle weight up to 2,270kg at speeds up to 70 km/h.
Whilst no longer approved at 100km/h, the Ironman Hybrid Barrier has been crash tested to the superseded Standard
NCHRP 350, TL-3 - 2,000kg vehicle, 100km/h at 25 degrees. This test shows the extra capacity of the system, this impact
has 80% more energy than the MASH TL-2 test and the deflection was 1.9m, only 28% more than the MASH TL-2
Deflection.
Barrier Segments
An Ironman Hybrid Barrier installation is constructed from a series of individual barrier segments. Each segment is
constructed from steel with four concrete inserts attached to the underside of the barrier. The dimensions of each
segment are:
Installed length
4.15m
Segment Width
546mm
Segment Height
813mm
Weight
925kg
The ends of each section are constructed with knuckles that interlock with those of other segments. The end knuckles
are vertically aligned to accept a steel connecting pin. The pin securely joins the sections for maximum impact
performance. The sections can swivel at the pin for easy positioning around work areas.
Limiting deflection spacers are to be installed to reduce the deflection and movement in the joints, they may only be
omitted where a tighter radius deployment is required.
The Ironman Hybrid Barrier is constructed in a unique shape. The sloping ribbed side walls interact with an impacting
vehicle in a way that resists penetration, vaulting, and under-riding. Each section contains four concrete ballast blocks
that are contained between the bottom rub rails providing weight and stability to reduce the deflection of the
freestanding Barrier.
