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 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…

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 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…

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…

This brief Guide provides advice on the proportion of cutback to be added to conventional bitumen to ensure that an even coating of bitumen is achieved under a variety of climatic and traffic conditions. Notes are provided to assist users when to…

This Pavement Work Tip provides a guide to calculate the volume of liquid bituminous binders relative to a standard temperature of 15°C.

This Pavement Work Tip describes the use of bitumen emulsion for dust laying on unsealed granular pavements to reduce dust nuisance, maintenance costs and loss of pavement material.

Progress towards the development of an integrated specification for Bitumens, Multigrades and Polymer Modified Binders (PMBs) has been achieved by the Austroads Binders project group in 2001/2002. Contributions to this task have been made in the…

This report has been prepared by the Austroads Emulsion Project to provide general information on the use and application of bitumen emulsions in Australia and New Zealand. The information contained herein has been compiled from surveys and project…
