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 Standards may also be withdrawn.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 Standards can be found by visiting the Standards Web Shop 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  yea r, and the mon thl y mag azi ne, The Global Standard , has a full listing of revisions and amendments published each month. Australian Standards and other products and services developed by Standards Australia are published and distributed under contract by SAI Global, which operates the Standards Web Shop. TM

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 [email protected], or write to the Chief  Executive, Standards Australia, GPO Box 5420, Sydney, NSW 2001.

PREFACE

This Standard was prepared by the Standards Australia Committee CE-006, Asphalt and Sprayed Surfacing, to supersede AS 2150—1995,  Hot mix asphal asp halt  t . The objective of this Standard is to provide manufacturers, specifiers and designers of  asphalt mixes with requirements for the manufacture and placing of asphalt for use in pavements. This Standard is not intended for use as a project specification. Project specifications for most road pavement applications are covered by standard specifications of state road authorities and local government. A guide to project specifications is provided in the  Austro  Aus troads ads Framewor Fram eworkk for Specifyi Spec ifying ng Asphalt  Asp halt  and the Australian Asphalt Pavement Association Nat Association  Nation ional al Asph A sphalt alt Specific Spe cificatio ation n.  .   m   o   c  .    l   a    b   o    l   g    i   a   s  .   e   r   o    t   s   o    f   n    i    /    /   :   p    t    t    h    t   a   n   o    i   s   r   e   v    l    l   u    f   e    h    t   s   s   e   c   c    A  .   e    l   p   m   a   s   e   g   a   p    6   e   e   r    f   a   s    i   s    i    h    T

Reference to this Standard may be made in specifications for minor works, in which case the Standard may be used to determine appropriate selection of materials, asphalt manufacture and standards of workmanship. The objective of this revision is to incorporate improvements based on user experience and reflect technical developments taking place in the industry. Major changes to the previous edition are as follows: (a)

Requirements for for mineral filler have have been introduced to replace replace AS 2357,  Mineral   Mine ral   fillers  fill ers for asphalt  asp halt ..

(b)

Grading envelopes have been revised.

(c)

Mix design requirements for volumetric volumetric properties based on gyratory compaction compaction have been introduced.

(d)

Mix design design requirements requirements for the Hubbard Hubbard Field Field Method Method of compaction have been been deleted.

(e)

Requirements for asphalt spreading, compaction and finished surface properties have been incorporated to replace the asphalt placing requirements that were previously referred to in AS 2734, Asp 2734,  Asphalt  halt  (hot-mixed ) paving   — Guide Guide to good practice. practice .

Since the early 1990s joint programs of AUSTROADS, the Australian Asphalt Pavement Association (AAPA) and the ARRB Transport Research Ltd (ARRB TR) have led to the development of new test methods for asphalt. These methods form the basis of the Selection & design of asphalt mixes: mixes :  Austral  Aus tralian ian provisi pro visiona onall guide gui de,, published by Austroads as APRG Report No 18.

Guidance on basis of payment for asphalt work is given in Appendix C.

2 REFERENCED DOCUMENTS

The documents referred to in this Standard are listed in Appendix D. 3 DEFINITIONS

For the purpose of this Standard the definitions below apply. 3.1 Added filler

A fine granular material, the majority of which passes a 0.075 mm sieve, which is added to an asphalt mix to supplement or modify the properties of filler in the mixture. 3.2 Adhesion agent

A substance used for the purpose of promoting the adhesion between a bituminous binder and aggregate. The term usually refers to adhesion in the presence of water. 3.3 Aggregate 3.3.1 Coarse aggregate
