This report is the second in a series which examines the properties of Australian bitumens from around Australia. Thirty-one bitumens from around Australia were subjected to a range of test procedures. These included viscosity measurement at a range of temperatures, durability testing, fractionation according to chemical properties, determination of softening point and penetration, and the calculation of various derived parameters. Almost half the bitumens failed to comply with specifications.
