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…

This test method sets out the procedure for determining the amount of binder drain-off likely to occur in an asphalt mix during storage and transport. The method may be used to determine the amount of binder drain-off at the maximum mixing…

This method describes the procedure for the recovery of sprayed seal samples from the pavement without disturbing the sealing aggregate orientation. The method stipulates how the void content of the sample is determined.

This test method sets out the procedure for assessing the degree of absorption of a primer or primerbinder by a given road gravel in bituminous surfacing work.

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 test method details the requirements for determining the flexural stiffness, phase angle, dissipated energy per cycle, cycles to failure and cumulative dissipated energy at failure of asphalt subjected to repeated flexure by cyclical four-point…
