TERRITORY AND MUNICIPAL SERVICES
PREFACE
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 infrastructure standards and specifications for practice in the ACT.
This present document is part of the ACT Trunk Road Infrastructure Technical Specifications (TRITS) series
spanning the broad scope of road infrastructure development and management in the ACT:

This ACT Trunk Road Infrastructure Technical Specification No. 04 – FLEXIBLE PAVEMENT
CONSTRUCTION prescribes the detailed practices for construction of flexible pavements in the ACT. 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.

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.
