Perceptual Countermeasure Treatments to Reduce Crash Risks in Tunnels
29 maart 2022 · 1 uur 2 min
Road tunnels are major pieces of infrastructure across the road network, and the number of tunnels is expected to increase in the coming years. Although they are relatively safe, a significant number of crashes occur on the approaches to and within tunnels. Lees meer
Austroads commissioned the University of New South Wales, Research Centre for Integrated Transport Innovation (rCITI) to investigate and evaluate the application of low-cost perceptual countermeasure (PCM) treatments in road tunnel environments as a means of improving driver speed behaviour, alertness and lane discipline, thereby reducing crash risk. The project involved two key research activities.
Research Activity 1 involved a systematic literature review and stakeholder consultation. Based on the outputs of these activities, three PCM treatments were selected for evaluation in a virtual reality driving simulator: Striped Wall Pattern; Rumble Strips (Edgeline and Centreline); and Pacemaker Lighting.
Research Activity 2 involved an experimental study conducted in the virtual reality driving simulator, located at rCITI. The virtual 3D environment for the driving simulator was based on the cross-sectional layout and alignments of the Sydney Harbour Tunnel. Driving performance data as well as subjective feedback from participants relating to their interaction with the PCM treatments were collected and analysed.
This webinar provides an overview of the two research activities and the key findings deriving from them. It is presented by Professor Michael Regan, Julius Secadiningrat, Dr. Prasannah Prabhakharan, and Mitchell Cunningham.

Benefits and Costs of Providing a Minimum Physical Infrastructure Standard for the Operation of Automated Driving
17 maart 2022 · 1 uur
Physical road infrastructure such as pavement markings and signals may have an important role to play to support the uptake of automated vehicles (AVs). Austroads has recently completed a project to provide road agencies with clear advice on investing in physical infrastructure to support the operation of AVs. Lees meer
This webinar, presented by Andrew Somers, Simon Xue and Elnaz Irannezhad, provides a detailed overview of the advice that addresses which infrastructure types should be prioritised for investment, as well as the timing and scale for that investment.
The advice has been developed against a backdrop of significant uncertainty around the future of AVs. These uncertainties include the year high-level AVs will become market-ready and the level of reliance of future AVs on physical infrastructures. To inform the development of the advice, the project first undertook an uptake forecast, an infrastructure assessment and economic analysis.
Having accounted for the various uncertainties of future AVs, the project has found the greatest return can be achieved by investments that will:
support current lower capability AVs
offer some advantages for human drivers
be strategically relevant to future higher-level AVs.

Road Authority Data for Connected and Automated Vehicles
9 december 2021 · 46 min
The Austroads Road Authority Data for Connected and Automated Vehicles (RADCAV) project studied the provision of agency-owned data to connected and automated vehicles (CAVs) addressing six high-priority data sets: roadworks, incidents, variable speed limit signs and lane control signals, static speed limits, traffic signals, and heavy vehicle access restrictions. Lees meer
This webinar, presented by Vibeke Matthews and David Yee, details a data provision framework that can be used by an agency to build capability in providing data to vehicles. The framework consists of the following components:
Capability model – a model that describes the spectrum of capabilities for the provision of agency data relative to vehicle and road agency capability over time. This ranges from Day 0.5 Capability (decision and actions made by vehicle controller), to Day 4 Capability (decisions and actions made by the vehicle).
Reference conceptual architecture – a series of outputs that describe the business architecture and information systems architecture necessary to provide agency data to vehicles at various levels of capability.
Implementation guidance – advice on how to use the Capability Model and Reference Conceptual Architecture as part of a process to improve an agency’s data provision capabilities.
The data provision framework is flexible and does not prescribe one end-state for agencies. Agencies have the freedom to choose a target state that suits their desired outcome, available funds, and appetite for change. It also caters for changes in vehicle capability over time, given that the introduction of higher-capability vehicles may be some years away.

National Specification for Crumb Rubber Binders in Asphalt and Seals
6 oktober 2021 · 1 uur 5 min
Australia and New Zealand produce about 510,000 tonnes of end‑of‑life tyres annually. Crumb rubber derived from end‑of‑life tyres has been used in Australia for several decades to enhance the performance of binders used in sprayed seals but prior to 2017 the use of crumb rubber in asphalt pavements was limited. Lees meer
Due to the lack of crumb rubber binder grades suitable for use in asphalt in the Austroads national polymer modified binder (PMB) specification (ATS 3110), two Australian jurisdictions and the Australian Flexible Pavement Association recently developed specifications for crumb rubber binders for use in asphalt which were based on tests and testing protocols used in Arizona and California.
This webinar, presented by Robert Urquhart, focuses on the outcomes of an Austroads research project which investigated whether the crumb rubber binders that were trialled in asphalt could be specified in terms of the tests and testing protocols used to specify other types of PMBs in the Austroads national PMB specification. Specification requirements have also been proposed for a binder containing 9% crumb rubber by weight which could be used in sprayed sealing applications.
The webinar also discusses the results of laboratory asphalt performance tests which investigated the effects of the amount of crumb rubber in a binder on asphalt performance.

Evaluating the Rutting Performance of Binders
16 september 2021 · 56 min
Asphalt pavements are a major component of the Australian and New Zealand road networks. Road agencies in Australia and New Zealand have been putting great efforts to produce pavements which perform and are long-lasting. This has led to the development of national specifications to ensure materials of suitable quality are used for road construction. Lees meer
Austroads ATS 3110 is used as a national performance-based specification for polymer modified binders (PMBs). The specification includes the consistency 6% (at 60 °C) property to evaluate the relative performance of a binder to resist rutting, as it is one of the major failure modes of asphalt pavements.
Consistency 6% tests are currently conducted using the elastometer instrument that was developed in Australia specifically for these tests. This instrument, however, is no longer being manufactured and the supplier is no longer providing technical support for existing instruments. A new test method has therefore been developed to determine consistency 6% properties using a dynamic shear rheometer (DSR) rather than the elastometer. The DSR is widely used to test bituminous binders and other materials across the world.
Presented by Young Choi, this webinar details the outcomes of the Austroads research project which was conducted to develop the DSR consistency 6% test method. The project work included an extensive literature review, equipment investigations, optimisation of test procedures and validation studies using many different types of binders. These studies were conducted to ensure that the new DSR test method is equivalent to the current elastometer test method.

Comparing the movement of commodities, domestically and internationally, helps to identify potential action areas to support Australian supply chain efficiency, competitiveness and resilience. As part of the Commonwealth international benchmarking project, the Supply Chain Benchmarking Dashboard was developed as a joint initiative between CSIRO and the Department of Infrastructure, Transport, Regional Development and Communications (the department). Lees meer
The dashboard is planned for release in the second half of 2021, and provides modelling and insights on Australian supply chain performance to:
support data-led decision-making to inform policy, investment and operational outcomes for government and industry
provide a national picture of supply chain performance across a wide range of metrics, commodities and regions
provide a comprehensive evidence base for international comparison.
This webinar demonstrates how users will be able to compare supply chain metrics across commodities, different transportation paths or segments in supply chains (e.g. producer to distributor, or distribution centre to port) and in different regions or locations (currently LGAs, states and territories).
The dashboard displays aggregated outputs from the Transport Network Strategic Investment Tool (TraNSIT) – a computer modelling tool developed by CSIRO that performs mass optimal routing of vehicle movements between thousands of enterprises. For each origin/destination enterprise pair, the model selects the least-cost travel path as well as the optimal vehicle configuration, allowing for road access and conditions, driver fatigue regulations and vehicle decoupling costs. The model outputs information on freight paths as well as detailed transport costs. Following release of the first iteration, stakeholder engagement is planned to gain feedback to further refine the model to best meet the needs of users.

Use of Recycled Plastics in Road Surfacing
10 augustus 2021 · 1 uur 3 min
The ban on the export of recycled waste plastic by the Australian government has led to interest in the use of recycled waste plastic in road surfacing applications. Austroads has published a report, Interim guidelines for the use of recycled waste plastic in local government road surfacing applications, to assist local government in the use and procurement of road surfacing products incorporating recycled waste plastic. Lees meer
This webinar, presented by Azeem Remtulla and Steve Halligan provides key information from the interim guidelines, discusses the status of the use of recycled waste plastic in road surfacing applications, the methods for the addition of recycled waste plastic into bituminous binders and asphalt along with limitations on the use of recycled waste plastic and proposes a methodology to the procurement of products incorporating recycled waste plastic.
The webinar also discusses surfacing applications for local council roads and propose a framework for comparing the properties of conventional asphalt to alternative asphalt mixes containing recycled waste plastic. This framework is based on current state road authority (SRA) and local government asphalt specifications and includes proposed tests to compare the performance properties of conventional asphalt against alternative asphalt mixes.
Worked hypothetical examples of the procurement and assessment process for asphalt incorporating recycled waste plastic as an alternative to conventional asphalt are also shared.

Technical Basis of Changes to Guide to Pavement Technology
3 augustus 2021 · 1 uur 2 min
Austroads has published two technical reports drawing together the research underpinning changes made to key components of the Guide to Pavement Technology. Lees meer
The reports detail the technical basis for changes made to Guide to Pavement Technology Part 2: Pavement Structural Design and Guide to Pavement Technology Part 5: Pavement Evaluation and Treatment Design.
This webinar, presented by Dr Michael Moffatt and Dr Geoff Jameson, outlines the technical basis of the changes made to Parts 2 and 5 since the last versions of the technical basis reports were published in 2008.
The 2017 edition of Part 2 included improvements to the design of flexible pavements, significant revision to the procedures used to calculate the design traffic, new procedures for the design of pavements with lime-stabilised subgrades and improved methods to predict the in-service fatigue life of cemented materials and estimate asphalt and cemented material design moduli.
The Guide to Pavement Technology Part 5 provides guidance on the selection and design of strengthening treatments to rehabilitate pavements. This is an integral part of managing a road network. The most recent edition of the guide enhanced the design procedure and expanded its use to a broad range of strengthening treatments, including asphalt overlays, inlays, major patchings and stabilisation of pavement layers and subgrade. The procedure is identical to the mechanistic-empirical procedure for the design of new pavements (detailed in Part 2) with the addition of an initial phase which determines the properties of the materials in the road-bed.

Next Generation Asset Data Collection: Road Pavement Performance
22 juni 2021 · 1 uur 2 min
The increasing pace of change of technology brings considerable promise of more data, of a higher quality, captured for a lower cost. This has the potential to improve the asset management of roads by enabling better decision making and providing a more complete picture of asset performance. Lees meer
These benefits, however, are not automatic. For asset managers, it can be difficult to know what technology is available and how the benefits compare to costs. There is also often considerable friction in moving to new approaches as existing processes and systems are tailored for the status quo. Perhaps the biggest hurdle is confidence in moving from an existing approach to having trust in the unknown.
In response to this need to understand the emerging technologies available, the cost-effectiveness of these technologies, and the implications of transitioning from existing to new approaches, Austroads has developed a research report on next generation data collection technologies for road pavement assets.
With specific reference to road pavement assets, this webinar takes attendees through:
The key themes across the data required to inform asset management decisions.
The current state of data collection technologies.
The interconnected ecosystem of emerging data collection technologies.
A structured framework for evaluating the cost-effectiveness of emerging data collection technologies.
Insights from the application of the evaluation framework and implications for future approaches to data collection.
Presented by David Jansen, Susan Chamberlain, Ella Hingston, Dr Colin Kemp and Trevor Chiang.

Options for Managing the Impacts of Aged Heavy Vehicles
27 mei 2021 · 1 uur 3 min
The freight industry is critical to the economy, and for many sectors it is heavy vehicles that underpin freight movements and prosperity. Lees meer
The average age of trucks in Australia and New Zealand is among the highest in the developed world. The oldest trucks are associated with higher environmental and health costs than newer trucks, yet these have been poorly quantified to date. Managing these issues is important to maintaining the freight industry’s social license.
Austroads has published a research report which analyses the impacts of an ageing heavy vehicle fleet and explores measures that have been used to manage this challenge in Australasia and internationally.

An Overview of the New Guide to Road Design Parts 1 and 7
25 mei 2021 · 58 min
Austroads has recently completed a project to consolidate the previous Guide to Road Design Part 1: Introduction to Road Design, Part 2: Design Considerations and Part 8: Process and Documentation into a new Part 1: Objectives of Road Design. Lees meer
This update to Part 1 of the Guide to Road Design provides practitioners with a detailed description of the critical aspects of road design and essentially combines the former parts 1, 2 and 8 into one single part. This will enable Part 2 to be utilised for network design considerations in a future update and the removal of Part 8 of the Guide.
In addition, a new Part 7: New and Emerging Treatments has been created to provide information to practitioners using emerging treatments which are known to provide some benefit from a safety and/or operational perspective but have not yet produced evidence for predominant contexts.
Part 7 contains design-related knowledge, findings from research and practical experiences about new, emerging and innovative treatments. This is a holding place for information about these treatments where full guidance is not available, for all road environments or until learning from implementation/trials is captured. The intention is for this information to be migrated to the respective parts 1 to 6 of the Guide when comprehensive evidence and dimensional guidance is available.
This webinar, presented by Noel O’Callaghan and Malcolm Mak, provides an overview of the new parts 1 and 7 and explain the links to other Austroads guides as well as jurisdictional supplements.

Paving our ways
13 mei 2021 · 1 uur 5 min
This webinar presents a book “Paving Our Ways”, which references Austroads’ research and provides a comprehensive international history of the world’s pavements, running from the earliest human settlements to the present day. No previous book has covered such a broad canvass. Lees meer
The book is written for general and technically oriented readers, tracing the human and social aspects of pavement development and use and providing detailed technical background. It also caters to students of engineering and transport wishing to broaden their knowledge of their profession or taking a course in the history and sociology of engineering.
“Paving Our Ways” provides interesting and curious asides about the stranger aspects of pavements. It explores the controversies surrounding the development of macadam pavements and, later, of asphalt pavements in a way that provides many insights into modern pavements. It also examines the subsequent competition between pavements using bituminous or cementitious binders.
The book covers three major time zones. The first is from the times of the Egyptian pharaohs to the end of the Roman era, the second is from the Middle Ages to the beginning of the First World War during which people like Tresaguet, Telford and McAdam had major impacts, and the third is from the end of the First World War to the present time when motorised trucks and machinery dramatically changed the way the pavements were made and used.
Looking back on the way current pavement technologies evolved, the authors of the book Maxwell Lay, formerly Director ConnectEast and Australian Road Research Board, John Metcalf, Formerly Louisiana State University, USA and Kieran Sharp, Road Eng. Assoc. of Asia and Australasia show how Australian practice relates to international practice.

Austroads Technical Specifications for Roadworks and Bridgeworks
6 mei 2021 · 55 min
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. Lees meer
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.

Network Operation Planning: Case Studies and Capability Building
22 april 2021 · 56 min
Network operation planning aims to guide the day-to-day operation and development of the road network. These management activities are regularly completed and documented through the development of Network Operation Plans (NOPs), which link policy objectives while managing competing transport and land use priorities. This intent of NOPs is generally agreed, but the way and level of application varies across the jurisdictions in Australia and New Zealand. The recent adoption of the Movement and Place (M&P) Framework in most of these jurisdictions has also influenced NOPs. Lees meer
Austroads has led a review to understand current NOP practices and provide material to build capabilities in state and local government agencies to increase NOP use and implementation. The approach to increase NOP use and application consisted of a review of relevant literature, five case studies in four jurisdictions and a detailed review of the Network Fit Assessment Tool. There was also engagement with state transport agencies.
The project has produced an online Reference Material Library to help those looking to develop or evolve NOP processes.
The webinar, presented by Andrew Somers, Will Fooks and Alex Blackett, covers:
an overview of the activities undertaken as part of this project.
a summary of the takeaways from the review of current practices.
an introduction to the Online Library.
