2 AS/NZS :2014 This Australian/New Zealand standard was prepared by joint Technical Committee CE-006, Asphalt and Sprayed Surfacing. It was approved on behalf of the Council of Standards Australia on 9 October 2014 and on behalf of the Council of Standards New Zealand on 10 October 2014 and published on 27 October The following are represented on Committee CE-006: ARRB Group Australian Road Research Board Australian Asphalt Pavement Association Australian Chamber of Commerce and Industry Austroads Civil Engineering Testing Association, New Zealand National Association of Testing Authorities Australia Roading New Zealand Keeping standards 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 Standards may also be withdrawn.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 joint Australian/New Zealand standards can be found by visiting the standards webshop in Australia at or Standards New Zealand s website at Alternatively, Standards Australia publishes an annual printed catalogue with full details of all current standards. For more frequent listings or notification of revisions, amendments, and withdrawals, Standards Australia and Standards New Zealand offer a number of update options. For information about these services, users should contact their respective national standards organisation. We also welcome suggestions for improvement in our standards, and especially encourage readers to notify us immediately of any apparent inaccuracies or ambiguities. Please address your comments to the Chief Executive of either Standards Australia or Standards New Zealand at the address shown on the title page. This standard was issued in draft form for comment as DR AS/NZS

5 1 AS/NZS :2014 Australian/New Zealand Standard TM AS/NZS :2014 Methods of sampling and testing asphalt Method 8: Voids and volumetric properties of compacted asphalt mixes PREFACE This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee CE-006, Asphalt and Sprayed Surfacing, to supersede AS , Methods of sampling and testing asphalt, Method 8: Voids and density relationships for compacted asphalt mixes. The objective of this revision is to adopt the same terminology used in aggregate test methods and to amend the scope with respect to air void content in relation to field compaction testing. METHOD 1 SCOPE This Standard sets out the method for determining the following properties of compacted asphalt: (a) Percentage air voids from separately determined values of bulk density and maximum density. (b) Absorbed binder, effective binder, maximum theoretical density, voids in the mineral aggregate, and voids filled with binder where the proportions of component materials are known. NOTE: The relationship between these properties is demonstrated in Appendix A. Where the air void content of in-situ compacted asphalt is required, for compaction compliance testing, determine the air void content in accordance with AS/NZS NOTE: The air void content can be determined using either this Standard or AS/NZS This Standard is intended for laboratory compacted asphalt and field samples of asphalt for investigation. AS/NZS is intended where percentage compaction and percentage in-situ air voids are determined for compaction compliance testing. 2 REFERENCED DOCUMENTS The following documents are referred to in this Standard: AS 1141 Methods for sampling and testing aggregates Method 5: Particle density and water absorption of fine aggregate Method 6.1: Particle density and water absorption of coarse aggregate Weighing-in-water method Method 6.2: Particle density and water absorption of coarse aggregate Pycnometer method COPYRIGHT
