SNZ AS/NZS 3845.1
Road safety barrier systems and devices Part 1: Road safety barrier systems
|Publication Date:||9 September 2015|
This Standard sets out the requirements for both permanent and temporary road safety barrier systems including-
(a) longitudinal road safety barriers (rigid, semi-rigid and flexible);
(c) crash cushions;
(d) interfaces, including transitions; and
(e) longitudinal barrier gates.
NOTE: Bollards, pedestrian fences and channelizers, truck or trailer mounted attenuators, truck underrun barriers, sign support structures and poles are specified in AS/NZS 3845.2*.
The intention of this Standard is to ensure that road safety barriers and systems are crashworthy when impacted by a vehicle under specified conditions and in most cases provide redirection and containment capability when impacted by a vehicle or provide controlled absorption of the kinetic energy of a vehicle that is on a collision course with a more hazardous obstacle or with other road users.
This Standard includes the following:
(i) Testing methods and data.
(ii) Considerations in the evaluation process.
(iii) Manufacturing requirements.
(iv) Issues to be addressed in specifying road safety barrier systems including documentation required.
(v) Erection and maintenance practices necessary to achieve expected performance.
(vi) Minimum site conditions (cross slope, placement of kerbs or similar) that enable the system to have acceptable system performance when impacted.
(vii) Steps to evaluate the nature of repairs necessary following a crash.
This Standard makes significant reference to MASH and NCHRP 350. It also references some relevant European CEN Standards.
NOTE: Refer to the Commentary in Paragraph A1 of Appendix A for further details about barrier classification types.
