Keeping Standards up-to-date up-to-date Standards are living documents which reflect progress in science, technology and systems. To maintain their currency, all Standards are periodically reviewed, and new editions are published. Between editions, amendments may be issued. Standards may also be withdrawn. It is important that readers assure themselves they are using a current Standard, which should include any amendments which may have been published since the Standard was purchased. Detailed information about Standards can be found by visiting the Standards Australia web site at www.standards.com.au and looking up the relevant Standard in the on-line catalogue. Alternatively, the printed Catalogue provides information current at 1 January each year, and the monthly magazine, The Australian Standard , has a full listing of revisions and amendments published each month. We also welcome suggestions for improvement in our Standards, and especially encourage readers to notify us immediately of any apparent inaccuracies or ambiguities. Contact us via email at

The objective of this Standard is to provide users and specifiers of aggregate with a basis for specifying requirements for aggregates intended for use in gabion wire baskets and wire mattresses. This Standard covers regional differences in environment, materials and practice and provision has been made to allow, in the works specification, for changes to some limits and procedures. There are materials that do not comply with this Standard but have proven to be satisfactory in service. Such materials should be supplied under a works specification only, without reference to this Standard. The term ‘informative’ has been used in this Standard to define the application of the appendix to which it applies. An ‘informative’ appendix is for information and guidance only.

This Standard provides a basis for specifying requirements for aggregates intended for use in gabion baskets and wire mattresses. The requirements relate to quality of rock and other properties of coarse aggregate. A coarse aggregate may be produced from rock, gravel, metallurgical slag, recycled material or suitable synthetic materials. 2 APPLICATION This Standard shall be used in conjunction with a works specification for contract purposes. While a number of the requirements nominated in this Standard are basic, the specifier shall make a selection from the options available in this Standard, or from alternative test methods and limits (which may be from Australian Standards or other appropriate Standards) for incorporation into a works specification. The basic requirements for all a ggregates are given in Clauses 7 to 9. The selection of test procedures and test limits, and the frequency at which individual tests are required, shall be determined by the individual works specification. The works specification should specify all the tests appropriate to the source rock or the tender samples, or both. The whole range of tests should not be applied to control acceptance of the product during the performance of a contract. For contractual purposes, the works specification is bi nding. In some cases a contract document uses terms such as ‘material complying with AS 2758.4’, without providing a works specification. In such instances, the supplier shall attempt to obtain further details from the purchaser. In the continued absence of a works specification, material will be deemed to comply with this Standard if the supplier operates a quality system complying with AS/NZS ISO 9002 and can pr ovide test data from a laboratory accredited to SAA HB18.25 showing that material to be supplied fulfils the requirements of Clauses 7 to 9 of this Standard 3 REFERENCED DOCUMENTS AS 1141 141 1141 1141.3 .3.1 .1 1141 1141.3 .3.2 .2 1141.1 1141.14 4 1141 1141.2 .22 2 1141 1141.2 .23 3 1141 1141.2 .25 5 1141.2 1141.26 6 1141.3 1141.30 0 1141.3 1141.32 2
