The aim of Part 3 of the Austroads Guide to Asset Management (Asset Strategies) is to provide guidance on the frameworks and principles of asset strategies. Asset strategies articulate the proposed management of the capacity, condition and use of road system assets to achieve the level of road system performance which is acceptable, affordable and sustainable to meet the needs of stakeholders and the community. The focus of Part 3 is to assist road agencies to develop performance-driven asset management strategies which achieve community-driven outcomes. The Guide presents an integrated strategy framework comprising: an overarching road system management strategy, a road investment strategy, an infrastructure preservation strategy and road use management strategies.

The aim of Part 7 of the Guide to Asset Management is to provide guidance on the application of asset management concepts and principles for the management of a broad range of diverse road related assets. The strategy framework is applicable to all road system assets. Guidance on managing the specific performance characteristics of pavements and structures is provided in Parts 5 and 6 respectively of the Austroads Guide to Asset Management.

The focus of this document is on how to best manage the physical bridge assets. It provides guidance on the establishment and maintenance of bridge asset inventories, and on the monitoring of asset performance. It discusses the need for agencies to measure asset performance against objectives, and therefore is primarily concerned with condition data collection and performance modelling at a network level. PDF availabe for purchase.

Asset Valuation and Audit is the title of part 8 of the Austroads Guide to Asset Management. It provides a comprehensive guidance for asset managers in the road industry. Part 8 Asset Valuation and Audit provides guidance on how to undertake an asset valuation to assist the asset manager with long-term asset and financial management requirements, how an auditor undertakes an audit of infrastructure and how to present information on financial sustainability of the agency to external stakeholders and other customers by use of public reports and other media. Part 8 Asset Valuation and Audit complements the Australian Infrastructure Financial Management Guidelines published by the Institute of Public Works Engineering Australia.

This document is part 2 of Guide to Asset Management, and provides guidance on how community and stakeholder requirements can and should influence asset management undertaken by road agencies. As roads are provided as a service to the community, community and stakeholder requirements are the means by which that service is defined. Only through the identification, translation and integration of these requirements (as appropriate) into organisational and asset objectives can road agencies target resources effectively to deliver that service. The direction and clarity provided by an effective framework for understanding community benefits and expectations (i.e. requirements), aids in the development of policies and strategies related to road asset management and performance. With an emphasis on current Australian and New Zealand practice this part provides: 1. an understanding of why it is important to have community and stakeholder input to asset management; 2. an overview of issues and approaches to obtaining and considering community and stakeholder requirements for asset management; 3. advice on how to establish and link community and stakeholder requirements to road agency outcomes.

This document contains guidelines for, and background notes on, network level measurement and reporting of deflection data, for road network management purposes in Australia and New Zealand. The guidelines discuss the frequency and scope of network deflection surveys, including issues such as selection of longitudinal sampling intervals or sampling proportions for deflection surveys. The guidelines are intended as a basis for a consistent approach in Australia and New Zealand. A glossary of terms used in network level assessment of pavement strength is also included.

This document contains guidelines for and background notes on measurement and reporting of rutting or transverse profiles for road network management purposes in Australia and New Zealand. The guidelines define rutting as a longitudinal surface depression usually in a wheel path. The guidelines have been prepared in the context of measuring rutting either manually with a straight edge or using a vehicle mounted non-contact multi-sensor transverse profile measurement device. Regardless of the method of measurement, the guidelines express a preference for rut depth to be reported with reference to a 2 m straight edge. This is consistent with the HDM-4 approach. A standard reporting interval of 100 m is favoured. The guidelines discuss the frequency and extent of network rutting surveys, and are intended as a basis for the preparation of specifications for surveys of network rutting. Verification procedures for profilometers, and limits on repeatability and bias for rutting reports are included. The document also discusses the uses of rutting data in road pavement management at network and project levels and provides guidance on analysis techniques for rutting data for different applications. A glossary of terms used in measuring road pavement rutting is also included.

This document contains guidelines for and background notes on network level measurement and reporting of pavement cracking data for road network management purposes in Australia and New Zealand. The guidelines discuss the types and causes of cracking, the frequency and scope of network cracking surveys, and the methods available for network level cracking surveys. The guidelines describe four current principal methodologies for measuring surface cracking at a network level in Australia and New Zealand, viz. detailed walk-over inspections, drive-over windscreen surveys, manual post-interpretation of video images of pavement surfaces, and fully automated techniques involving high-resolution imaging and automated crack recognition. The guidelines recognise and define three parameters for reporting cracking, viz. dominant crack type, severity (crack width), and extent (proportion of total surface area cracked). The guidelines are intended as a basis for a consistent approach in Australia and New Zealand. Verification procedures for cracking measurement methods are covered, and repeatability and bias are briefly discussed. A glossary of terms used in network level assessment of road surface cracking and a summary of a literature review of practices for collecting cracking data are included. (a)

This report contains guidelines for and background notes on the conduct of response type and profile-based roughness measurement for road network management purposes in Australia and New Zealand. The guidelines define roughness as being concerned with road surface profile wavelengths between 0.5 metres and 50 metres. The guidelines describe two broad measures of roughness, viz NAASRA Roughness Meter (NRM roughness values in counts per kilometre) and the International Roughness Index (expressed in units of metres per kilometre), and mark the introduction to Australasia of Lane IRI as a standard form of reporting road pavement roughness. A standard reporting interval of 100 metres is favoured. The guidelines discuss the frequency and extent of network roughness surveys, and are intended as a basis for the preparation of specifications for network roughness surveys. Verification procedures for inertial profilometers, testing frequencies, and limits on repeatability and bias for roughness reports are included. A glossary of terms used in measuring road roughness is also included. (a) Austroads Project AP1009

This document introduces the Austroads Guide to Asset Management, the aim of which is to offer guidance on how to best manage physical road infrastructure. The Guide covers various aspects of asset management including how to determine and plan to accommodate stakeholder/community expectations, formulate and review asset strategies, develop works programs, assess asset performance and undertake asset valuation and audit. Whilst the focus of the Guide to Asset Management is on the management of the physical road assets, the importance of total transport system management, which covers all activities concerned with the provision, operation, maintenance, renewal and disposal of transport infrastructure assets, is duly recognised. Road asset owners and managers are therefore encouraged to adopt a comprehensive range of coordinated activities, from transport planning, through design, implementation and operations in order to maximise community benefits. The Guide complements the Austroads Publication AP-R202/02 Integrated Asset Management Guidelines for Road Networks, which describes in detail the integrated asset management planning processes and recommended implementation stages aimed at achieving business improvements within road agencies.

This document is designed to assist the practitioner in navigating through the Part 5 sub-parts of the Austroads Guide to Asset Management. It contains a brief overview of the topic without going into detail, as detailed discussion on key issues are offered in other volumes of the Part 5 series. The measurement of pavement performance and its significance is briefly discussed. The section on data management touches on the key aspects of data classification, level of service and information quality levels. The reader may gain a general overview of the key issues of data management, data types and classification. Some guidance is given regarding the consideration of the types of data selected and the frequency of data collection. To underline the general nature of the discussion, the term 'pavement management system' (PMS) was avoided and the generic term 'decision support system' (DSS) was used. The terminology is also useful to keep the topic in context; i.e. a PMS is a specific application of a DSS for one asset class, i.e. the pavement. The overview covers the working of a decision support system and the classification of DSS. The brief discussion of various models assists the reader to orientate in this otherwise complex territory. The section also includes brief definitions of key terminology covering the key components of a DSS, such as triggers, works effects, maintenance standards, etc.
