Structural analysis has progressed a long way from hand calculations and the use of distribution factors. From the first computer methods, grid and grillage analysis techniques evolved, leading through progressive enhancements to the advanced 3D…

Some old bridges in Australia were constructed with a deck system consisting of non-composite concrete slab over steel girders. The paper herein presents the methodology for structural retrofitting/ strengthening of these existing bridges based on…

The economic vitality of Auckland depends upon the movement of people and freight around the city’s motorways and the Auckland Harbour Bridge (AHB) is a crucial component of the network. Traffic loads derived from weigh-in-motion (WIM) data measured…

There are 5094 bridges and bridge size culverts under the jurisdiction of the Roads and Traffic Authority (RTA) NSW. More than 50% of these bridges were built before 1976 and design load was significantly lower than the T44 design load in accordance…

More sustainable bridge infrastructure can be achieved by eliminating costly and unnecessary replacement or overly zealous upgrading of ageing bridges. Estimates of current safety of bridges or their remaining service life are critically dependent…

This report presents a review of the available structural design methods for foamed bitumen pavements, as a first step in the development of thickness design procedures. Six design procedures were found in the literature, most of them based on well…

This report presents the test results of bitumens used across different states in Australia. This database will be useful in identifying possible trends in properties associated with recent changes in the manufacture of Australian bitumens and…

This report is the second in a series which examines the properties of Australian bitumens from around Australia. Thirty-one bitumens from around Australia were subjected to a range of test procedures. These included viscosity measurement at a range…

A significant factor contributing to the establishment of Australia’s large network of surfaced roads has been the successful application of sprayed sealing technology, including the selection of treatments, design of the treatments and application…

Austroads Project No: TT1358: Review of Structural Design Procedures for Foamed Bitumen Pavements proposed a method for the thickness design of foamed bitumen to be adopted in principle by Austroads. Foamed bitumen is a mixture of hot bitumen, water…
