​​​​Surface types

We use a combination of asphalt and chipseal road surfaces across Hamilton.

Asphalt tends to be used on roads that have high volumes of traffic (i.e. over 15,000 vehicles per day) or areas that have high turning stress (for example, cul-de-sac heads and certain T junctions).

Chipseal tends to be used on roads with lower volumes of traffic, which are less affected by heavy traffic.

Our surfacing process for these are different and this is detailed further down the page.

Planned work

We will begin our chipseal resurfacing work programme in January 2021. We plan to reseal 69 streets, covering around 20km over the summer period. 

The sites are selected based on age and condition of street. We generally chipseal every 10-15 years, depending on the condition on the road. Chipseal renewals are completed over summer when there is less traffic on the roads, and when sunny and dry weather is more likely.

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

The chipseal process

  1. Minor repairs were carried out throughout September, October and November. These patches are called pre-seal repairs. 
  2. Our Infrastructure Alliance team will notify residents in the street about a week before work begins via a letter drop. The chipseal work is generally completed within one day only.
  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 regularly swept away, and road marking will be repainted if the markings disappear due to chip loss. Temporary traffic management will be removed a couple of weeks after the chipseal takes place.
  6. As many as three additional sweeps may follow in the next six to nine months to remove loose chip.

The asphalt process

  1. Our Infrastructure Alliance team will notify the residents in the street about two weeks before work begins and confirm the intended dates of work.
  2. Excavation (milling) of existing surface is undertaken. 
  3. Laying of new asphalt surface is completed. This work may be done at night as these are generally streets with high traffic volumes.
  4. Line markings, traffic loops and special surfaces (for example, green cycle lane markings) are reinstated.
  5. Temporary traffic management is removed.
