The New Zealand Transport Agency (NZTA) has announced that they will use Epoxy Modified Open-Graded Porous Asphalt (EMOGPA) instead of chip seal on the PP2Ō Expressway “in response to growing traffic demands now and into the future.”
In 2013, based on traffic modelling presented, it was determined that chip seal was the most appropriate and cost effective surface for the expressway.
The Mayor says he’s pleased the Transport Agency has made this decision as it will benefit both local community living near the PP2Ō Expressway and motorists.
“As I understand it, EMOGPA is longer-lasting than chip seal and will make for a much smoother driving experience. It drains better and faster during storm events and will help reduce the traffic noise for people living near the expressway.”
