Austroads: Transport Research and Trends

In Australia and New Zealand, bituminous binders used in road construction are tested prior to use to ensure they will perform satisfactorily during road construction/maintenance. Some of the Australian Standards that are used for these tests have not been updated for 25 years which can make it difficult for testing laboratories to adhere to them.

In this webinar Dr Robert Urquhart presents an overview of an Austroads project which provided expert technical input into the revision of seven Australian Standards – four bituminous emulsion, one polymer modified binder and two cutback bitumen related Australian Standard test methods. They were revised by the Australian Standards Committee CH-025 ‘Bitumen and related products for roadmaking’ between August 2020 and September 2022.

Following topics are covered in the session:

• the process used to update an Australian Standard
• the main changes to each of the seven Standards
• the status of revision of each Standard
