This publication contains information on several highway right-of-way assets including pavements, bridges, culverts, guardrails, and drainage structures. It describes the functional characteristics of each asset type, the data that are usually collected about the asset, general data collection methods, equipment and/or technology that is employed to acquire the data, the formats and standards applied to data transfer and storage, how the information is used for condition assessment, and suggests performance and condition standards. Table of contents available for download.

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.

The theme of the 6th National Conference on Transportation Asset Management was Making Asset Management Work in Your Organization. Sessions were tailored to the varied needs of the participants, with presentations oriented for individuals just getting started in asset management, for individuals who have had some experience with the concepts but want to learn more, and for experienced users who want to enhance their current capabilities. In addition, several sessions were organized to address the special needs of large, complex organizations, small organizations, and transit and rail issues. Other sessions covered asset management applications in varied transportation agencies, establishing and using performance measures, analytical issues in asset management, data collection for asset management, and best practices in transportation asset management. This circular summarizes the contents of the conference sessions and presentations. The moderator for each session prepared a summary of his or her session as well as summaries of the individual topics included in the session. The intent of this circular is to provide a record and reference of the conference topics so that future deliberations and conferences can build on these efforts.

This report focuses on linking data collection to decision-making processes as a part of asset management. The research team identified four States for indepth case studies on asset management. They explored the agencies' data collection approaches and documented their decision-making practices. The research team found that asset management needs varied by agency, and the team proposes the development of a data collection framework to facilitate a more effective and efficient implementation of asset management.

This report summarizes the proceedings of a peer exchange on the use of asset management techniques in the metropolitan planning process. The peer exchange brought together representatives from state DOTs with representatives from MPOs to share knowledge about asset management and discuss the potential for implementation.

The 2006 edition of the Infrastructure Asset Valuation and Depreciation Guideline provides an agreed and consistent approach for the valuation and depreciation of infrastructure assets including roads, water supply, sewerage, storm water, parks and recreation, land drainage, property, cultural and heritage assets. The general principles are also applicable to telecommunications and energy assets.

An Austroads report on processes by which road agencies can streamline their decision-making. The report outlines the analytic hierarchy process (AHP) and life cycle cost analysis (LCCA) as a means for prioritizing objectives based on competing criteria and economic factors.

A literature review produced by Austroads in 2006, reporting on the purposes and techniques for community consultations at road agencies.

This report, published by Austroads in 2006, provides guidance for processing results of level-of-service community consultation to more efficiently build a framework of performance measures for maintenance activities.
