Accessibility is broadly defined as the variety of opportunities provided to people through efficient arrangement of land use and various modes of transport. It measures the ease with which people are able to find and reach the best suited…

This paper considers how several recent pedestrian-oriented bridges, all on Auckland’s Western Ring Route, provide new connections or re-establish severed connections between communities. As the architect involved in these bridges, I will also…

Priorities in bridge engineering are changing. The imperative has shifted subtly from minimum cost to “more for less”, requiring a more holistic approach to sustainable delivery which offers best value to the economy and society as a whole over the…

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…
