Spray sealing is used as a preventative surface treatment for roads that are still in good structural condition. It extends the life of the road surface and helps avoid costly, disruptive repairs down the track.
Process
Spray sealing involves a layer of hot bitumen being sprayed on the road, followed by a layer of crushed rock. The rock is then pressed into the bitumen to create a sealed surface that helps protect the road from water damage or movement.
After the road has been rolled, most of the loose rocks will be swept up, however it is completely normal for some to remain. Sweeping takes place a few days after sealing, so its expected that loose rocks will be present during this time.As cars drive over the newly sealed road, they will help push those rocks further into the road and create a more compact surface that could be achieved with just the roller machinery alone.
The rock layer is a crucial part of the spray sealing process because it provides the road's structural strength and acts as a durable wearing surface that protects the underlying layers.
Benefits:
- Flexible and helps prevent cracks
- Great for areas showing early signs of surface deterioration
- More environmentally friendly and cost-effective than asphalt
What to expect during road works
If your street has been scheduled for resurfacing, you will receive a notification letter informing you of the works. This will explain the date and time the roadworks is planned, where it will take place, how property access may be impacted and who to contact if you have any further questions.
We ask that you keep children and pets away from machinery, avoid using water near the gutters and consider parking on nearby streets to avoid delays or reduced access to your property.
Once the works are complete, please drive carefully and slowly on the new road surface and avoid turning your steering wheel while stationary.
