The move towards performance based specifications (PBS) for the nation s vehicle fleet is expected to result in increased stressing of pavement surfacings. The extent of surface stressing is currently unknown and the capacity of surfacing treatments…

The report documents the procedures used to commission a Cooper wheel tracking apparatus. Practical issues are discussed with emphasis on achieving a repeatable outcome. This involved checking the accuracy of the loading system and the deformation…

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…

A pilot study examined the feasibility of using laboratory produced mix compaction curves to indicate the relative workability (ease of compaction) of asphalt mixes in the field. Five mixes of different expected workabilities were used. A roller…

An Austroads national workshop on asphalt was held to assist development of a research program and identify supplier and user risks which affect quality and performance. Delegates identified key issues under the themes of: mix design and…

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…

Austroads works towards uniformity of practice in respect of design, construction and user aspects of roads and bridges and with this purpose in view, publishes guides and procedures.

Traffic Engineering Practice, first published in 1965, is a…

Unsealed roads are the largest single component of the Australian road network, in terms of lane kilometres. The purpose of this document is to record the results of an Austroads project on the management of unsealed roads The main activities in the…

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 test method sets out the procedure for determining the quantity of loose aggregate on the surface of a sprayed seal.
