This report is the first progress report of a four year project which aims to improve the Austroads procedures for the mix and structural design of foamed bitumen stabilised materials.

The report summarises the test methods drafted to date and…

Bitumen, an important component used in road construction in Australia and New Zealand, is manufactured from a finite, non-renewable crude oil resource. A number of commercially available alternative binders and bitumen extended binders have been…

This document provides a guide to the selection of modified binders including multigrade bitumens for different treatments and service conditions, and to assist in the use and interpretation of the Austroads Specification Framework for Polymer…

The 2011 Austroads Guide to Pavement Technology Part 5: Pavement Evaluation and Treatment Design includes an interim procedure for the thickness design of foamed bitumen stabilised (FBS) pavements. This project aimed to validate the interim…

This report provides guidance in the development of a level of service framework for maintenance and improvement activities based on community consultation with a focus on internal road agency processes, specifically on how to integrate the findings…

This report outlines a process for community consultation and specific techniques to assess community needs and priorities, including affordability and trade offs, and methodologies for defining levels of service criteria for road serving a range of…

This report provides a review of community consultation techniques used by various road agencies in Australia and overseas. The review addresses the definition of community consultation, the purpose of consultation and its phases and describes…

This report analyses the existing vehicle fleet mix and forecast future fleet growth and reviews the appropriate indicators for the level of service for freight vehicles. It also compiles the current practices in improving the efficiency of freight…

This report gives information on the development of a procedure to fractionate bitumen using an Iatroscan liquid chromatography system, and also presents test results on a range of Australian bitumens. An introduction discusses the topic of bitumen…

Australia s specification for paving grade bitumen AS 2008 evolved in the early 1970s from a penetration grading system to one with viscosity control at 60 Degrees Celsius. In support of this primary performance control property, penetration at 25…
