This work tip provides guidance on binder sampling to ensure that consistent and reliably representative samples are obtained so that any test results: represent, as near as practicable, an average of a consignment or batch

Guide to Pavement Technology Part 2: Pavement Structural Design provides advice for the structural design of sealed road pavements. The advice has been generally developed from the approaches followed by the Austroads member agencies. However, as it…

Austroads has completed a project to replace the obsolete gyratory compactors used in design and quality control testing of asphalt mixes and update its Guide to Pavement Technology Part 4B: Asphalt. Austroads asphalt mix design procedure currently…

This report presents the final outcome of an investigation to review, analysis and identify suitable sealed granular pavement sections for inclusion in the LTPP study. The investigation identified 69 sealed granular pavement test sections across…

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…

The suitability of the CoreLok device was assessed for estimating the bulk density of compacted asphalt specimens. The device encloses a sample in a plastic bag which is subjected to vacuum and sealed. Results were compared to saturated surface dry…

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…

This report describes an investigation into the temperature sensitivity and repeatability of test results obtained using a Cooper wheel tracking device. One set of specimens was tested at the standard temperature (60 Degrees Celsius) and two other…

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…

An inter-laboratory proficiency study was conducted based on the resilient modulus test. Participants from Australia and New Zealand were required to test nine asphalt cylinders prepared by a single laboratory. All participants used a MATTA to…
