Here’s an interesting snippit from the Nelson City Council
For the first time, the top layer of asphalt removed from a Nelson road has been recycled, with excellent results.
The resurfacing of over a kilometre of Rutherford Street saw over 1,000 tonnes of asphalt millings removed before the new surface was laid. Rather than dump it, Council and contractor Downer agreed to look at recycling it to surface rural roads.
A trial of laying the millings through a paver was carried out on a portion of Enner Glynn Road with great success. The relaid asphalt millings produce a hard wearing, durable pavement that’s easy to maintain.
The recycling meant there was virtually zero waste to the Rutherford Street project and the method will now be used in other jobs.
