1、AS/NZS 3845:1999 Australian/New Zealand Standard Road safety barrier systems AS/NZS 3845:1999 This Joint Australian/New Zealand Standard was prepared by Joint Technical Committee CE/33, Road Safety Barrier Systems. It was approved on behalf of the Council of Standards Australia on 9 October 1998 and
2、 on behalf of the Council of Standards New Zealand on 12 October 1998. It was published on 5 January 1999.

4、niversity of Technology Transit New Zealand Review of Standards. To keep abreast of progress in industry, Joint Australian/ New Zealand Standards are subject to periodic review and are kept up to date by the issue of amendments or new editions as necessary. It is important therefore that Standards u
5、sers ensure that they are in possession of the latest edition, and any amendments thereto. Full details of all Joint Standards and related publications will be found in the Standards Australia and Standards New Zealand Catalogue of Publications; this information is supplemented each month by the mag
6、azines The Australian Standard and Standards New Zealand, which subscribing members receive, and which give details of new publications, new editions and amendments, and of withdrawn Standards. Suggestions for improvements to Joint Standards, addressed to the head office of either Standards Australi
7、a or Standards New Zealand, are welcomed. Notifi cation of any inaccuracy or ambiguity found in a Joint Australian/New Zealand Standard should be made without delay in order that the matter may be investigated and appropriate action taken.

The objective of this Standard is to provide users with (a)issues that
10、have to be addressed when specifying the installation of these devices; (b)erection and maintenance practices necessary to achieve an acceptable level of performance; (c)the process necessary to assess the nature of repairs to a road safety barrier system, or to a crash attenuator system following a
11、 crash; and (d)methods to test road safety barrier and crash attenuator systems. This Standard also provides details of non-patented road safety barrier systems that are deemed to comply with this Standard. This Standard describes a means of evaluating road safety barrier systems, based on the best
12、practices identified by the Committee. The National Cooperative Highway Research Program (NCHRP) of the United States Report Number 350 has been adopted as the basis of testing. This Standard is to be read in conjunction with NCHRP Report 350. Reference to CEN Standards is made in NCHRP 350. The Com
13、mittee notes that the provisions are rudimentary and steps are being taken which may lead to a mutual recognition of tests in future NCHRP and CEN documents. Statements expressed in mandatory terms in notes to tables are deemed to be requirements of this Standard. The terms normative and informative
14、 have been used in this Standard to define the application of the appendix to which they apply. A normative appendix is an integral part of a Standard, whereas an informative appendix is only for information and guidance.

34、downloaded from Standard Sharing 5AS/NZS 3845:1999 FOREWORD The intent of this Standard is to provide a framework that unites the many parties involved in the provision of road safety barrier systems and crash attenuators, so that the completed installations provide acceptable performance to the co
35、mmunity of road users over the length of time the barrier systems are expected to operate. The function of these devices is to improve road safety by reducing the consequences of crashes. However, it should be recognized that these devices are themselves a hazard; they have the potential to cause se
36、rious injuries. The intention of this Standard is that these devices are only installed at locations where the risk with the device installed is significantly less than the risk without the device. The duty of care to be exercised is emphasized. The community of road users includes people in a varie
37、ty of vehicles which vary in size, mass and methods of propulsion. What should be noted is that the users of these vehicles have different levels of protection, especially pedal cyclists and motorcyclists. The community of road users also includes pedestrians and those involved in the various constr
38、uction, operational and maintenance activities that occur within the road reserve. At some sites, the community of road users should be extended to include those whose activities require them to abut the road reserve.

39、 Standard Road safety barrier systems S E C T I O N1S C O P EA N DG E N E R A L 1.1SCOPEThis Standard sets out the requirements for roadside devices that provide some degree of redirection and containment capability when impacted by a vehicle, or provide controlled absorption of the kinetic energy o
40、f a vehicle that is on a collision course with some significant obstacle. This Standard includes the following: (a)Methods and data to test road safety barrier and crash cushion systems. (b)Issues to be addressed in specifying these devices. (c)Erection and maintenance practices necessary to achieve
41、 acceptable performance. (d)Steps to evaluate the nature of repairs necessary for road safety barrier systems following a crash. The Standard also provides details of non-patented road safety barriers that are deemed to comply with this Standard. Where the terms vehicle or impacting vehicles are ref
42、erred to in this Standard for the consideration of effects on or by a road safety barrier system, these terms include the following: (i)Motorized vehicles, such as cars, trucks and motorcycles. (ii)Non-motorized vehicles, such as pedal cycles and horse-drawn vehicles. (iii)Operators, drivers and rid
43、ers of vehicles specified in Items (i) and (ii) whether attached or unattached to their vehicle. (iv)Any other road users, considered appropriate to the conditions being assessed. This Standard is to be read in conjunction with NCHRP Report Number 350. NOTE: For commentary on this Section, see Appen
44、dix A. 1.2APPLICATIONThis Standard applies to both permanent road safety barrier systems and road safety barrier systems designed to be readily erected and dismantled. It also applies to devices meant for the applications given in Table 1.2. This Standard does not apply to the following: (a)Road saf
45、ety barrier systems erected for special purposes, such as motor racing, or where special permit vehicles are the design focus. (b)Where individual elements of a road safety barrier system are used for special purposes, such as protection of gas tanks and delineation of car parks. (c)Pedestrian fence
46、s. (d)Truck-mounted attenuators (TMAs). (e)The comparative performance of road safety barrier systems or the preferred type of road safety barrier system to be installed.

47、rlongitudinallyor transversely, or with related issues considered in positioning of road safety barriers, such as sight distance, drainage, aesthetics, cost and environmental matters. A fundamental requirement in the application of this Standard shall be the use of risk management techniques. These
48、techniques shall be used to evaluate the hazards and the associated risks to the community of road users. Where appropriate, the neighbours to a road shall be included in the analysis. The outcome sought shall be a balanced decision that considers the probable benefits, the resources available and t
49、he competing investment opportunities.
