Minimum Deployment
Ironman Hybrid Safety Barrier installations require a minimum deployment length of 57.5mm, 11no. Hybrid Barriers
plus 2 TL-2 SLED end treatments, to safely contain and redirect at MASH TL-2.
Length of Need
Saferoads Ironman Hybrid Barrier installations utilise SLED TL-2 end treatments to ensure occupant safety in the event
of an impact to the end of a barrier installation.
The Length of Need begins at the joint between the 4
th
and 5
th
Hybrid Barrier, 22.5m downstream from the nose of
the SLED. The End Length of Need is 22.5m Upstream from the downstream end of the System.
Crash testing revealed that a 2,270kg Dodge Ram was successfully redirected when impacting the plastic modules of
the Upstream SLED at 70km/h on a 20° angle. The deflection of the system was 3.5m, whilst the system will redirect
vehicles from the first steel barrier, to rely on the 1.49m deflection the BLON starts at the end of the 4
th
Barrier.
