Relationships between cutter oil properties and sprayed seal performance

This study investigated the relationship between cutter oil properties and sprayed seal performance so that this information could be used as a basis for updating Australian Standard 3568. AS 3568 specifies the properties of four different types of oils which can be used to reduce the viscosity of binders during sprayed seal construction. The standard has not been updated since 1999 and needs to be revised to be more performance-based so that it can include currently available commercial products. During the study, seven commercially available oils were initially subjected to a range of currently specified AS 3568 tests. The results obtained for each oil were then compared to the results obtained in four different laboratory sprayed seal performance tests which were performed after each of the oils had been blended with a single sample of C170 bitumen. Correlations were found between the AS 3568-specified final boiling point and viscosity at 40 °C results obtained for each of the neat oils, and the results obtained in the laboratory performance tests. A number of changes to AS 3568 have been proposed based on the results obtained in the study and input from the Austroads Bituminous Surfacings Working Group (BSWG).
