National Survey of Bitumens: 2006 to 2012

A database of the properties of bitumens used in Australia has been collated over the course of this project (2006/12). This database will be useful in identifying possible trends in properties associated with changes in the manufacture of…

Fourth National Survey of Australian Bitumens

This report is the fourth in a series which examines the properties of bitumens used in Australia. The bitumen testing program was undertaken to develop a database of selected bitumen samples dating back to 1956. This database has been used to…

Investigation into the Properties of Alternative Surfacing Binders and Bitumen Extending Binders

Bitumen is a major component used in the construction of roads in Australia and New Zealand. As it can only be manufactured from a small number of the crude oils in the world, the future supply and cost of bitumen will be directly linked to the…

Asphalt Permeability
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…
Review of AS2008 from an Emulsion and PMB Manufacturing Perspective
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…
The Asphaltene content of Australian Bitumens Part 1: Testing of Pre-1992 Samples
The report presents data on the asphaltene content of samples manufactured between 1956 and 1991. Asphaltene content is one of the main chemical properties used to characterise bitumen. Bitumens are generally regarded as colloids whereby clusters of…
Development of a Procedure to Chemically Characterise Bitumens using the Iatroscan
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…
Austroads Test Method: Summary for 2005/06
Austroads has produced a series of test methods developed from various technical projects, principally in the bituminous materials area (asphalt, binders, slurry and sprayed seals). The Austroads system of managing the test methods has enabled…
Specification Framework for Polymer Modified Binders and Multigrade Bitumens
This Specification Framework for Polymer Modified Binders (PMBs) and Multigrade Bitumens has been produced by an Austroads Project Group. The specification is based on a set of test procedures that have been in use throughout Australia for several…
