A database of the properties of bitumens used in Australia has been collated over the course of this project (2006/12). This database will be useful in identifying possible trends in properties associated with changes in the manufacture of…
This report describes studies of the effects of test conditions on vertical polished aggregate friction value (PAFV) results and the results of a proficiency study which was conducted to determine a preliminary PAFV value for UK aggregate. The…
Cutting solvents have been traditionally added to binders used in sprayed sealing in Australia and New Zealand to ensure that effective adhesion occurs between binder and aggregate. Recent Polymer modified binder (PMB) sealing failures, which have…
This report is the fourth in a series which examines the properties of bitumens used in Australia. The bitumen testing program was undertaken to develop a database of selected bitumen samples dating back to 1956. This database has been used to…
