The management of Australia and New Zealand’s bridge stock involves the development of forward works programs for periods up to, and longer than, ten years into the future. The scheduling of maintenance, rehabilitation and replacement, forms part of…

There is significant pressure in Australia to improve freight productivity through the national reform agenda. A key component of the reform plan is to improve access to the road network for heavy vehicle operators. Assessment of bridge capacity is…

This report investigates the origins of the current Unconfined Compressive Strength (UCS) criteria that differentiates modified granular materials from bound materials. Based on the review, a number of changes to the UCS design criteria are…

In modern bridge structures, bridge bearings and expansion joints are commonly the source of most maintenance and performance issues. In some situations their performance can lead to the closure/failure of major structures and their maintenance can…

Over the last decade a considerable amount of research effort has been focussed on the development of a repeated load triaxial (RLT) test procedure to assist practitioners in the use of natural and marginal unbound base/subbase materials in road…

This document is the combined output of two projects commissioned by Austroads to support improved consistency in Australia and New Zealand in inventory and condition data for road bridges, by developing a minimum set of inventory items, condition…

This report documents work undertaken in relation to the Austroads Business Systems Project BS.A.N.523 Salinity and Rising Water-Tables - Risks for Network Asset management. The purpose of the project was to identify the potential impact of dryland…

This technical report resulted from a study to develop Austroads guidelines on network level assessment and analysis of data on pavement structural condition. This report outlines the benefits of network level assessment of the structural condition,…

Road agency inventories in Australia and New Zealand include approximately 50,000 structures that are being managed as bridges. In Australia and New Zealand on arterial roads alone, the value of structures being managed as bridges exceeds A$10b, and…

Concrete durability is an increasingly important issue for road authorities because of the large population of ageing bridges and the decreasing funds available for construction and maintenance. The performance of bridges in the Australasian road…
