The new addition to the Ezy-Guard family is the Ezy-Guard Bridge Barrier System. Using a modified version of the MASH Test Level 4 Ezy-Guard High Containment system, the bridge barrier configuration is designed for bridges and structures requiring AS5100 compliant edge protection. The Ezy-Guard Bridge Barrier can be deck or side mounted to the bridge structure, saving valuable lane width.
It is compliant to AS 5100.2 - Low Performance Level, AS/NZS 3845.1, this is comparable to the MASH Test Level 2 containment level. MASH TL2 is a 2270kg vehicle impacting the barrier at 70km/h and 25˚ impact angle.
For locations with a posted speed higher than 70km/h, a reduced post spacing configuration of the system is available for the MASH TL3 compliance, this has the posts at 1m centres.
An Ezy-HC-Carriage is used to secure the Thrie-beam rails to the posts eliminating the requirement for blocking pieces, saving valuable lane width.
The Ezy-Guard Bridge Barrier is designed for minimal load transfer into the structure, reducing potential concrete damage in a crash. This means less road closures or need to repair concrete after impact damage.
There is also a lower impact risk to the vehicle occupants through the controlled yielding of the barrier posts.
An easy transition into Ezy-Guard 4 is achieved with a short 6m transition length. The shorter transition length results in returning to the MASH TL3 containment level when re-connecting to the Ezy-Guard 4 system.
