Local Road Resurfacing Underway

Like most things, roads deteriorate over time and need to be replaced. Warmer months are the best time to do this, and the Tararua Alliance have begun this year’s resurfacing programme for Tararua District Council Roads.

The seal on a road is like paint on your house - it keeps water out of the structure underneath and prevents further damage. Like paint, the seal breaks down over time and starts to let water in.

When the surface of a road starts to show signs of breaking down (e.g. cracking) it is time to reseal. The ideal time to reseal is just before any damage occurs, so your road may still look to be in good condition when we complete the reseal. It’s also done to restore the road’s skid resistance, which decreases over time as vehicle tyres polish the surface’s stones.

Tararua roads are generally resurfaced with a chip seal once every fifteen years on average. This can be more or less depending on the road’s characteristics.

The chip seal process:

Minor repairs are carried out to prepare the road for resealing and maximise the life of the new surface.

Hot bitumen is sprayed and stone sealing chips are spread and rolled in.

Traffic is then allowed on the road to bed in the new seal. This is a necessary and important part of the resurfacing.

Excess sealing chips are swept away and road marking is reinstated. Temporary traffic management will be removed at this time.

Additional sweeping of loose chip may follow in the next six months.

For your safety and that of others, and to protect the new pavement and seal, please observe the speed signs by sticking to the set limit- it’s only for a short distance.

We thank you for your patience while these vital works are carried out.
