New Zealand’s Port of Napier recently repaired a heavily deformed section of pavement in their Container Terminal by replacing the failed pavement with high-performance asphalt mix incorporating technology never before used in a base course anywhere in the world.

Local contractor, Higgins Contractors Limited (HB), of Napier removed the deformed pavement from a section of H8-
K1 and re-paved the area using Highly Modifi ed Asphalt (HiMA) technology developed by Kraton Polymers LLC.
