Rob Gaimster: Concrete New Zealand CEO on concrete roads being cheaper to maintain

Questions are being raised as to whether Aotearoa should take a page from the United States' book when it comes to our roads.  Concrete New Zealand-commissioned research shows road maintenance costs using the material are up to 62% lower than asphalt.  It also shows that, on average, concrete roads are 17% cheaper over 40 years.  Chief Executive, Rob Gaimster told Mike Hosking America has a good model, with half of their roads concrete.  He says New Zealand has a pothole crisis and is spending billions on roads but is still building in the same way.  LISTEN ABOVE See omnystudio.com/listener for privacy information.
