This webinar will give you an overview of an Austroads project that compared the test properties of seven commercially available cutter oils with their sprayed seal performance.
In Australia and New Zealand cutter oils are added to hot binders when sprayed seals are constructed at cooler temperatures to enhance the adhesion between binder and aggregate.
The research will inform an update to AS 3568 so it is a performance-based standard that will allow the use of currently available commercial oils. Australian jurisdictions use Australian Standard AS 3568 to specify the properties of cutter oils used during the construction of sprayed seals but it has not been updated since 1999. AS 3568 also currently specifies some materials which are no longer commercially available.
You’ll learn about the:
- results of the project
- types of cutter oils included in the study
- cutter oil test properties and their relationship to sprayed seal performance
- proposed changes to AS 3568 based on the results of the project and input from Austroads Bituminous Surfacings Working Group members.
Join in a live Q&A with our presenter to have your questions answered.
Presented by Robert Urquhart
Robert Urquhart is a Principal Technology Leaderin the Future Transport Infrastructure Group at ARRB. After obtaining his PhD in Physical Chemistry from the University of Melbourne, he worked in Bitumen Products Technologist and Bitumen Technical Manager roles at BP Bitumen Australia between 1997 and 2010. During these roles he was responsible for developing and improving BP Bitumen’s range of bitumen, bituminous emulsion and polymer modified bitumen products. Since 2010, Robert has been conducting research and contract work at ARRB into the properties of bituminous binders and their performance in sprayed seals and asphalt.
