Why reseal?

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

When the surface of a road starts to break down 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.

Roads generally are resurfaced with a chip seal except where the traffic volumes or pavement conditions justify otherwise. Roads that have previously have asphalt surfacing may be resealed with chip seal.

The chip seal process

  1. Minor repairs are carried out prior to resealing.
  2. The contractor will contact residents in the street about a week before work begins.
  3. Hot bitumen is sprayed and stone sealing chips are spread and rolled in.
  4. Traffic is then allowed on the road to bed the new seal.
  5. Excess sealing chips are swept away and road marking is reinstated within 48 hours. Temporary traffic management will be removed at this time.
  6. As many as three additional sweeps may follow in the next six months.

The asphalt surfacing process

  1. Minor repairs are carried out prior to resealing.
  2. Residents and businesses are advised of the work programme.
  3. Milling to remove the existing surface at joints and existing kerb is complete to enable a smooth transition from old to new.
  4. Laying new asphalt surface at sites. This work may be done at night as these are generally streets with high traffic volumes.
  5. Line markings, traffic loops and special surfaces are reinstated.
  6. Temporary traffic management is removed.
