9) What is the expected lifespan of
HighwayGuard™
?
HighwayGuard™
has an expected lifespan of over 20 years. This is dependent on maintenance regime
and site specific environment.
10) What is the smallest run of barrier and the largest available?
The permissible length of the system is unlimited but the barrier must be anchored at the end of each
run and intermediately as required by the system type.
The recommended minimum length of barrier is 10 sections (60m) to replicate test set up. Installing
with tested anchor spacing is recommended to replicate test deflections and working widths. There is
no maximum limit but consideration for works access must be given.
11) I need to achieve a really low deflection as I am working with limited space, what are my
options?
HighwayGuard™
Lowest Deflection System (LDS) might be the best option for this application. With the
increased anchor intervals at 12m spacing deflection is reduced. Refer to crash test deflection results
and it may be appropriate to risk assess the deflection figure using the calculated deflection tables in
this manual.
12) I want to install
HighwayGuard™
on a bridge deck, is this possible?
HighwayGuard™
can be installed on bridge decks in both permanent and temporary situations.
Depending on the project it may be possible to anchor either side of the bridge deck expansion joints.
Where anchoring on the bridge deck is required it may require project specific anchor details and
possibly a variable length
HighwayGuard™
section for the bridge expansion joint.
13)
What drainage capability does
HighwayGuard™
have?
The water drainage per 12m section is approximately 1.15sqm.
14)
How close to excavations can it be placed?
Anchors need to be a minimum of 0.68m away from excavation edge.
15)
Can access gaps be created in the middle of a long run of barrier?
The T-Connection allows section to be removed easily from a run by crane. All that needs to be done
is remove the security nut from two T-Connectors and lift the whole section vertically upwards.
