This edition of Austroads News has a run down on the latest Austroads reports and upcoming seminars and conferences.
Austroads is pleased to announce the appointment of Nick Koukoulas as the new Chief Executive for Austroads.
Nick was most recently Managing Director of BSI Group for Australia and New Zealand. The global British Standards Institution delivers standards-based solutions to help organisations improve their quality and performance, reduce their risk and achieve certification. Nick is an experienced Board Member and Graduate of the Australian Institute of Company Directors. He has had roles as a senior executive for national and multi-national market leaders in professional services, standards development, registered training organisations, maritime fire and safety, and importation and wholesale distribution.
Acting Austroads Chairman, Peter Duncan, said Austroads is pleased to have found a new Chief Executive of Nick’s calibre.
"We believe that, with his extensive experience in change management and integration projects, he will make a strong contribution to ensuring Austroads is responsive to the needs of its members and the Australasian road industry," Peter said.
Nick started in the position on Monday, 3 November.
Help Improve the Guide to Bridge Technology
The Austroads Bridge Technology Task Force wants to better understand how practitioners are using the Guide to Bridge Technology and how it can be improved.
Full details of the proposed specialist categories will be provided on the Austroads website next week with invitation to provide comment on the proposal.
A consultation kit will describe the proposed new categories, explain their development, and provide the minimum requirements that are proposed to be met for prequalification, the mutual recognition framework, and how the categories (and contractors prequalified in them) will be managed at the national level.
Submissions will be due by 19 December 2014.
Improving the Design of Foamed Bitumen Stabilised Pavements
Austroads Guide to Pavement Technology Part 5: Pavement Evaluation and Treatment Design includes an interim procedure for the thickness design of foamed bitumen stabilised (FBS) pavements. However, there are concerns that the interim procedure is not as well founded as those for conventional treatments due to a lack of performance data. The design method needs to be verified/modified with field performance to provide a more accurate prediction method.
In 2012 Austroads commissioned a project which aims to:
improve the Austroads procedures for the structural design of foamed bitumen stabilised materials for new pavements and structural rehabilitation treatments
identify distress modes of bitumen stabilised pavements from a series of trial sites
improve and harmonise national mix design procedures for bitumen stabilised materials.
In early October Austroads published a progress report on the project's developments and findings.
The report summarises the draft test methods which are currently being reviewed by road agencies and industry. It also describes research findings on the effect of mixing moisture content used in the mix design on modulus and the extent to which modulus varies due to laboratory compaction process.
The report also provides:
the construction and early-life performance monitoring of a trial section of a foamed bitumen stabilised pavement developed in October 2013 on the Newell Highway at Bellata, New South Wales
one year performance data for a trial section constructed on the Calder Freeway at Woodend, Victoria
the fatigue cracking of Port Wakefield Road, Virginia, South Australia within two years of opening to traffic
the latest performance data from Kewdale Road in Canning and the Kwinana Freeway in Perth, Western Australia.
Use of Recycled Aggregates has Economic and Environmental Benefits
The costs of sourcing traditional pavement materials are increasing as sources are being exhausted, haulage distances are increasing, and access to traditional sources is increasingly restricted. As a result, jurisdictions are seeking alternative solutions, one of which is the use of recycled materials.
Austroads has released a report that provides an estimate of the financial cost savings of incorporating recycled aggregates into pavement bases. It also sets out the environmental and social considerations associated with recycling and resource use.
Two detailed case studies examine the experience of a local council in New South Wales and industry in South Australia.
The report suggests there are significant economic and environmental benefits associated with the incorporation of recycled aggregates in pavement bases.
Ensuring Accurate Traffic Speed Deflectometer Data Collection
The ARRB Traffic Speed Deflectometer (TSD) uses seven Doppler lasers to monitor the response of a pavement to the application of a mass at highway speeds. The data collected provides continuous pavement deflection profiles, from which bearing capacity indices can be derived and pavement fatigue can be estimated. The high accuracy and resolution of the TSD enables engineers to pin point areas where the pavement may be subject to failure.
TSD technology is relatively new and Austroads has released two reports to assist member agencies in the accurate collection of data:
Austroads Road Safety Program Manager Leads New International Road Safety Group
Austroads Road Safety Program Manager, Iain Cameron, has been appointed Chair of a new OECD International Transport Forum Working Group established to reduce road fatalities and serious injuries by helping governments to implement a “safe system” approach.
The "Working Group on the Implementation of a Safe System Approach” will develop guidance for countries seeking to improve their road safety performance and ultimately eliminate road traffic as a cause of death or serious injuries.
Mr Cameron said that much progress had been made in the six years since the initial report, which could now be reviewed. “Countries would like some further advice and guidance. We can capture some of the progress [and] hear about the challenges,” Mr Cameron said. “We can put that together and provide some support for leaders in the countries.” You can see an interview with Iain Cameron in the video link above.
The working group comprises 28 top-level road safety experts from 23 countries and from the World Health Organisation, the World Bank, the International Road Assessment Programme (iRAP), the Global New Car Assessment Programme (Global NCAP) and the FIA Foundation.
The new Working Group will present an interim report in November 2015, coinciding with the half-way point of the United Nations Decade of Action on Road Safety 2010-20. The full life-cycle of the working group is two-years, and a final report will be completed by the end of 2016.
This short report explains why investing in maintenance at the right time can lead to significant reductions in future costs and supports the efficient management of maintenance. Actions that help obtain the best value from road maintenance include:
having a multi-year vision, models of evolution of network condition, service standards objectives and performance-based works contracts, and
understanding the availability of resources for future year and the wider impacts of maintenance funding on road users, society and the environment.
Austroads Receives Award from the Transportation Association of Canada
The Transportation Association of Canada (TAC) has recognised Austroads for its collaboration in and support of TAC’s work to advance the state of transportation knowledge in Canada. The award was presented to Austroads on the occasion of TAC's centennial celebration. TAC is a not-for-profit, membership-based association that provides a neutral forum to exchange ideas and information on technical guidelines and best practices related to transportation.
