Table of Content


 

This list is split into the following components:
    • Barriers
    • Terminals
    • Transitions
    • Gates (note a gate consists of a barrier and a transition)
    • Motorcyclist Protection

 

 
The listing does not cover traffic barriers on structures. Details on approved traffic barriers on structures and transitions can be found on the Main Roads website under Standard Drawings under the heading Traffic Barriers and Balustrading for Structures.

 

 
For each approved component a date of approval is shown if it is a proprietary product approved since 2001 or public domain product that has been modified since January 2009 and a design sheet is attached as a hyperlink to the component name.

 

 
Approved solid blockouts for use on W Beam barrier systems can be found in Annexure 603D of Specification 603 Safety & Traffic Barrier Systems.
 
 
Barrier System Assessment
 
Products that are to be assessed by Main Roads Western Australian shall be presented in the format required by the Austroads National Safety Barrier Assessment Panel.
 
 
Crash Testing

 

For barrier systems to be assessed by Main Roads Western Australia the barrier shall be crash tested as a minimum to NCHRP 350 - National Co-operative Highway Research Program Report (NCHRP) 350 "Recommended Procedures for the Safety Performance Evaluation of Highway Features".

 

 
Products tested to MASH 08 - "Manual for Assessing Safety Hardware, 2008" will also be acceptable.
Crash testing to CEN 1317 will also be considered particularly to the higher containment levels (H1 and above). Testing to normal containment levels (N1 and N2) will only be considered if the system has also been tested to NCHRP 350, MASH 08 or to CEN 1317 level H1 or above.
 
 
Acceptability
Successful passing of the required crash testing is only one element to barrier system acceptability.
Other elements considered by Main Roads are:
    • System performance
    • System maintenance
    • Whole of life considerations
 
Disclaimer
 
These sheets are intended to be used as a guide to the Designer and where they describe proprietary systems they do not take precedence over information contained within the Manufacturer's documentation other than where limitations or configurations have been specified.
Some systems have restrictions placed upon such as work zone barriers only or not to be used on new works.
Where indicated the systems shall be installed in configurations indicated in these sheets.

 

 
The list includes barrier systems that are no longer installed on new works but have been included for completeness.
