It is issued to clarify any exceptions or additional requirements for implementation in the ACT, and to identify relevant complementary documents. In many areas of road infrastructure construction and management, the ACT has adopted the relevant specifications of the NSW Roads and Maritime Services (formerly RTA NSW). The relevant RMS documents are identified and referenced in these ACT Trunk Road Infrastructure Technical Specifications. The works must be carried out according to the referenced RMS specifications with the exception of items detailed in the Technical Exception Clauses. Where any differences in practice exist between the RMS Specifications and this Trunk Road Infrastructure Technical Specification, the latter will prevail. The ACT Government replaces RMS where applicable as the Road Authority. ACT replaces NSW where applicable as the place where the work is conducted. Equivalent ACT authorised organisations and legislation replace NSW’s where applicable. Roads ACT’s athorised representative is equivalent to RMS’s principal.

Trunk Road Infrastructure Technical Specification No. 04 – Flexible Pavement Construction 1 TERRITORY AND MUNICIPAL SERVICES INTRODUCTION The Australian Capital Territory has adopted the Austroads Guides for provision and management of road and transport infrastructure. The Territory and Municipal Services Directorate has issued a revised series of documents to reflect this development in standards and specifications for practice in the ACT. The planning, design and management of Earthworks in the ACT must be implemented in general accordance with the Austroads Guide to Pavement Technology and in accordance with specific provisions of the ACT Trunk Road Infrastructure Standard No.6 - Pavement Design. The Australian Capital Territory has adopted the NSW Roads and Maritime Services (RMS - formerly RTA NSW) specifications for road works, including flexible pavement construction. Pavement construction must be carried out according to the referenced RMS specifications with the exception of items detailed in the Technical Exception Clauses. This ACT Trunk Road Infrastructure Technical Specification No. 04 – Flexible Pavement Construction prescribes the detailed practices that must be followed in the implementation of the relevant RMS specifications in the ACT. The works covered in this Section of the specification cover the construction of flexible pavements comprising crushed rock, gravel and suitable soil pavement layers, bituminous layers and surfacing. 1.1 SCOPE The works covered in this Section of the specification cover the construction of flexible pavements comprising crushed rock, gravel and suitable soil pavement layers, bituminous layers and surfacing. This Specification includes stabilised pavements but does not include gravel surfaced pavements. 1.2 STRUCTURE OF SPECIFICATION The Specification refers to a list of RMS Specifications. Each referenced RMS specification contains a more detailed scope statement. Exceptions and deviations from these are listed in the Technical Exception Clauses. 2 REFERENCE DOCUMENTS Reference documents include Austroads Guides, Australian Standards and RTA Test Methods. 2.1 LEGISLATIVE DOCUMENTS 2.2 GUIDELINES Austroads Documents Part 1: Introduction to Pavement Technology Part 2: Pavement Structural Design Part 3: Pavement Surfacings Part 4: Pavement Materials Part 4A: Granular Base and subbase Part 4B: Asphalt Part 4C: Materials for concrete road pavements Part 4D: Stabilised materials Part 4F: Bituminous binders Part 4G: Geotextiles and geogrids Part 4H: Test methods Part 4I: Earthworks materials Part 4J: Aggregate and source rock Part 4K: Seals Part 4L: Stabilising binders Part 5: Pavement Evaluation and Treatment Design Edition Click here to enter text./ Revision Click here to enter text.
