Introduction

HighwayGuard™ is a MASH 16 TL-3 compliant steel safety barrier. The 6m single barrier section, with

the unique T-Connector provides quicker installation, removal and separation of barrier sections. It

also offers the ability to remove sections within a run to create access gaps, replace damaged sections

or alter barrier runs.

HighwayGuard™ is an anchored steel safety barrier that can be used in temporary and permanent

applications.

Design Considerations

It is important that HighwayGuard™ is planned/designed and installed in accordance with this

manual and any approval/regulatory conditions placed upon its acceptance use in that territory.

Delineation

Reflective delineators may be required for both permanent and temporary applications. The

specification (size, shape, colour, position) can vary in accordance to meet local

regulations/requirements.

Drainage

HighwayGuard™ has a 10mm drainage gap underneath the barrier. Additional drainage provision

is provided at anchor points. The water drainage per 12m section is approximately 1.15sqm.

Pavement Types

HighwayGuard™ has been tested installed on asphalt pavement that is 150mm asphalt concrete

over a granular subbase.

Alternative ground conditions may be acceptable but could require different anchor solutions.

Install Lengths

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 60m to replicate test set up. Installing with tested

anchor spacing is recommended to replicate test deflections and working widths.

HIGHWAYGUARD.COM

Curves

The T-Connector can allow an approximate angle of up to 0.23° for vertical connections and 0.77°

between barrier sections for horizontal connections. Example horizontal curves;

Deflection/Clear Zone

HighwayGuard™ is designed to absorb energy when impacted. When impacted between anchors

deflection occurs. No hazards or obstacles should be in the deflection area such as kerbs, work

materials/equipment.

Vehicle roll should be considered with taller vehicles as these may protrude beyond the barrier

deflection during impact.

Crash Cushions/Other Connections

Crash cushions should be used when impact to either the approach or departure end of a run of

HighwayGuard™ may occur.

Current Crash cushions/ Connections available;

-Highway Care BG800™ Transition (MASH Crash tested)

-QuadGuard CZ (NCHRP 350 Engineered)

-Tau II (NCHRP 350 Engineered)

An engineered connection is one that has been designed and jointly agreed by Highway Care and

the crash cushion developer as acceptable for use. These may also require approval from relevant

road authorities –check road authority approval for guidance on acceptable options available in

your market.

Modifications

No modifications are allowed to HighwayGuard™ components without prior approval from

Highway Care.

Installation

HighwayGuard™ must be installed in accordance with this manual and with the latest state road

authority conditions. Where conflict arises road authority conditions take priority over this

manual.

Planning

Prior to starting an installation, it is recommended that the customer informs the installer of;

-Start/end positions and alignment requirements of each barrier run (including crash

cushions)

-Curvature (horizontal and vertical) required to ensure appropriate components available

-Installation site risks identified (e.g. overhead cables, bridges, tunnels, drilling limitations)

-Traffic management measures in place to ensure appropriate and safe working space
