Moisture damage in asphalt (also known as stripping) can significantly reduce the durability and strength of asphalt pavements, often resulting in expensive repairs. Hydrated lime is widely used in Australia to reduce the moisture susceptibility of…

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…

Hydrated lime is widely used in Australia to reduce the moisture susceptibility of asphalt mixes in service. However, the local asphalt industry is concerned about the sustainability of the continued use of hydrated lime in asphalt. This report…

This report details the testing of 21 Austroads jurisdictions mixes and one airport mix to develop a relationship between the Austroads Gyropac Gyratory compactor, which is now redundant, and the Servopac (setup to AS/NZS) and Superpave Gyratory…

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…

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…

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…
