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…

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…

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…
