Currently, most Austroads member agencies rely on their unique technical specifications for the delivery of roadworks and bridge projects. In many cases, these specifications have been developed over a number of years in consultation with local industry and suppliers.
While it is recognised that there will always be some requirements that will only apply to a single jurisdiction, standardising specifications (and the associated test methods) has the potential to improve work processes for road agencies, suppliers and contractors.
To increase efficiency for road agencies and industry and optimise compliance with contract requirements, 14 technical specifications have been published for all Austroads member agencies to use for the construction of roadworks and bridgeworks. These specifications are suitable for use with any general conditions of contract, including design and construct contracts. They are expected to be used in conjunction with supplementary local or contract specific requirements.
This webinar, presented by Richard Edwards, takes participants through the technical specifications development process and provides an overview of the structure and layout adopted for the specifications.
The Engineering Guideline to Bridge Asset Management was developed to provide specific asset management guidance for road bridges. The guideline promotes an engineering approach (engineering principles, knowledge, experience and modelling tools) as being the only robust method for understanding the current and future, condition and needs of a bridge network.
The guideline defines best practice asset management for bridges over their lifecycle in a manner that will provide a transparent link between investment and outcomes. It includes a specific and detailed asset management framework for bridges.
This webinar, presented by Barry Wright, Torill Pape and Peter Shaw, takes participants through the development of the guideline and provides an overview of the key principles and learnings contained in the guideline.
This webinar, presented on 30 April, gives an overview of ways to assess the safety of existing bridges beyond the Rating Factor approach of AS5100. It was presented by Dr Colin Caprani, Dr Mayer M Melhem and Professor Mark G Stewart.
This webinar, presented on 29 April 2020, discusses the merits of three options to advance the future of PBS access in Australia as it relates to bridges. It was presented by Angus Draheim, Matthew Bereni and Neal Lake.
This webinar provides an overview of an Austroads project that investigated whether cements with elevated limestone content would perform satisfactorily in ambient-cured and precast concretes subjected to aggressive exposure conditions.
The webinar was presented on 15 October 2019 by Dr Ahmad Shayan and Fred Andrews-Phaedonos.
This webinar outlines the findings of an Austroads geopolymer concrete project and a current update of the use, monitoring and specification of geopolymer concrete by VicRoads over the past nine years.
• geopolymer concrete, its constituents and how it is manufactured
• formulation and testing of numerous geopolymer recipes, and investigation of workability, strength development, mechanical behaviour, durability properties, abrasion resistance and ductility of reinforced geopolymer concrete
• the introduction of geopolymer concrete into VicRoads with several trial structural applications, general paving works and evaluation of performance.
The webinar was presented on 1 May 2018 by Dr Ahmad Shayan and Fred Andrews-Phaedonos.
