1.0 Introduction
Introducing MashFlex, a member of the Flexfence family,
the next generation wire rope safety barrier (WRSB),
providing superior motorist safety and more metres of
barrier for your dollar.
MashFlex is crash tested to the latest performance
standard, the Manual for Assessing Safety Hardware
(MASH) Test Level 3, making it compliant to the current
AS/NZS 3845.1:2015.
The superior design and clean lines of the MashFlex
WRSB have seen it become the road safety industry’s
preferred wire rope barrier. These design characteristics
have continued in this next generation of the product,
MashFlex, with an improved design and simplified
assembly sequence.
With the introduction of the iRAP Star Rating for a
highway’s safety, critical for a 5 Star rating is the separation
of oncoming vehicles and protection from roadside
hazards, WRSB has become a key countermeasure in
these designs. Cross-median accidents are typically
violent collisions with a high probability of multiple
serious injuries and death.
The straight alignment of the ropes allows for easy
installation and tensioning. Post footings are typically
concrete with a sleeve to form a recess. Once the anchors
and footings are poured, the ropes are cut to length,
stainless steel end fittings are machine swaged and the
ropes are tensioned.
MashFlex is a 4-rope barrier assessed in accordance with
MASH Test Level 3 (TL3) and TL4.
Test Level 3 comprises two tests, the heavy vehicle impact
is performed with a 2,270kg pick-up truck travelling at
100km/h and impacting the barrier at 25°, the purpose of
this test is to verify the barrier’s performance for impacts
involving pick-up trucks and SUVs.
The small vehicle impact is performed with an 1,100kg
car travelling at 100km/h and impacting the barrier at
25˚, the purpose of the small car test is to evaluate the
risks to the vehicle occupants when impacting a safety
barrier.
TL4 requires the evaluation of the barrier when impacted
by a 10,000kg rigid truck travelling at 90km/h and
impacting the barrier at 15°, the purpose of this test is
to evaluate the capacity of the barrier to contain and
redirect the vehicle.
