the testing undertaken by a reputable crash test organisation, and
the results certified as complying with an equivalent NCHRP Report 350 test level.
In addition, we also supply spare parts within set time frame in consideration for maintenance.
PERFORMANCE TESTS
The minimum performance level for road safety barrier systems installed on state highways is NCHRP Report 350 Test Level 3 (TL 3). The performance level of the road safety barrier systems approved for use on state highway roads is given in NZTA M23: Appendix A.
The minimum performance level required for road safety barriers on state highway bridges shall be determined by the method given in Appendix B, Section B3 of Transit New Zealand’s Bridge Manual.
DESIGN, LAYOUT, INSTALLATION AND MAINTENANCE OF ROAD SAFETY BARRIER SYSTEMS
Design
The design of all road safety barrier systems shall be compliant with the crash tested design or the barrier system configuration given approval under Section 3: Approval of Road Safety Barrier Systems.Changes to the crash tested/approved design/configuration will deem the barrier system noncompliant with this specification.
Layout
The layout of all road safety barrier systems should comply with the relevant guidelines:
(a) Roadside Safety Barriers
The layout of all roadside barriers shall be in accordance with the requirements of Section 7.3 of the SHGDM:Longitudinal Road Safety Barriers.
(b) Median Safety Barriers
The layout of all median barriers shall be in accordance with the requirements of Section 7.3.12 of the SHGDM:Median Barriers.
