NZTA has recently released a major update on bitumen testing.
“For many years New Zealand bitumen was based on an empirical Penetration based specification. However, changes to the crude oil feedstock used to manufacture bitumen, plus the importation of bitumens into New Zealand from other refiners who use other crude oil feedstock has meant that the empirical Penetration test could no longer be used to infer performance. This has led to the adoption of a performance-based specification for asphalt binders.”

Accurate characterization and selection of materials (aggregates and binders) is the first step in the SuperPave Mix Design procedure. Like many other jurisdictions worldwide, the latest NZTA specification have been modified to address the evolution of bitumen and are now based on AASHTO M 332 Standard for Performance-Graded Asphalt Binders.
