Asphalt: Sustainable Polymers - MacRebur®
MacRebur® polymers are derived from selected plastics and are designed for the extension and performance improvement of bitumen for asphalt. In use in over 30 countries, MacRebur products offer a significant improvement in the fatigue life of asphalt mixes, as well as an increase in the stiffness of modulus.
Profiled case studies include a range of applications including a local road two-lane resurfacing project in Norway, the use in AC20 asphalt surfacing for aprons at Auckland International Airport and other NZ based hardstand and local road applications where a sustainable pavement solution was a project benefit.
MacRebur case studies
-
MacRebur MR6, increasing performance of AC20 - Auckland International Airport
MacRebur MR6 was used to develop a high performing AC20 dense graded asphalt for Auckland International Airport apron areas on Stage 4 of the Fuel Network and “Checkpoint Charlie” upgrade. This case study outlines the use and application of MR6 in asphalt works (ensuring compliance with AASHTO M332 bitumen specification) and dual performance and sustainability benefits achieved.

MacRebur MR6, substitute polymer - Resurfacing Rogaland Region, Western Norway
MacRebur MR6 provided a substitute to a premium polymer modified bitumen mix for the Norwegian Roads Authority for a two-lane local road in Hommersakveien. This case study identifies the constructability advantages and benefits of using MacRebur MR6 as a binder, its performance and sustainability gains.
-
MacRebur MR8, used as a sustainable option - Ford Road, Taradale, Napier
As part of their sustainability initiatives, Napier City Council piloted MacRebur MR8 in the asphalt mix for the resurfacing of Ford Road, a busy commercial connecting road. This case study profiles the use and benefits of using MR8 polymer with AC10 asphalt mix composition and product performance.
