The future of Bitumen testing in New Zealand
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.”
