Council is responsible for managing over 590 kilometres of sealed road throughout the district, including the ongoing maintenance and rewnewal.
Our maintenance crews often find and repair faults, however due to the large size and rural nature of our district, there are sometimes faults that we are not aware of.
If you spot an issue that requires attention, such as potholes, blocked drains, or a broken footpath, please contact Customer Service during office hours. Our maintenance crew will then inspect and, if required, repair the fault.
Occasionally, during a peak rain and storm period, there may be some delay due to the large number of requests. Your patience is appreciated during these times.
In some instances, the problems are larger than a simple maintenance repair. These problems will be escalated to our Engineering Department for further investigation.
We undertake a detailed assessment of our road network every five years that looks at, analyses and condition scores both the seal (surface bitumen) and the pavement (the underlying crushed rock base of the road).
The rating system determines the life remaining in both the seal and pavement by quantifying a number of visible features such as:
- cracking (lateral, crocodile, transverse)
- stripping of aggregate from surface
- deterioration of bitumen binder
We use this rating system to develop treatments for roads and plan in advance which roads will require treatments and when.
When a road can no longer be repaired by maintenance, interventions such as seal renewals and pavement renewals are usually used.
A seal is the top 30-50mm of bitumen surfacing on the road. When a seal is at or near the end of its life, Council will reseal the road, by placing another seal on top of the old. It is important to ensure a road has a quality bitumen seal on its surface to prevent water penetrating the underlying pavement structure, and to provide a smooth and safe driving surface to road users.
Annually, Council undertakes a resealing program that reseals roughly 25 to 30 roads and restores the seal of the road to 'brand new'.
The Council does two types of reseal - a spray seal resurface, and a hotmix asphalt surface. A spray seal resurface involves a layer of bitumen with fine stone then rolled into the mix. This type of resurfacing is most suited to semi rural and rural roads at higher speeds and with minimal stopping or turning. A hotmix asphalt surface is used predominantly in urban areas to provide a durable surface resistant to stopping, braking, and turning, and a smooth ride at lower speeds.
The reconstruction of a road to replace a failed pavement is a much more costly and time consuming process than a seal renewal. Annually, Council annually undertakes 3 to 4 full road reconstructions. This usually happens when the road is 'falling apart' and the road is rutted and has lost its shape and strength. The two different types of reconstructions are granular pavement reconstruction and a deep life full asphalt reconstruction.
A granular pavement reconstruction is used for local and rural roads. The road is excavated out to around 300mm thick and replaced with new compacted rubble.
A deep life full asphalt reconstruction is used for major roads and is a similar construction to main roads throughout the district. The top 150mm or so is dug out and replaced entirely with bitumen to ensure the road is re-opened in 1 to 2 days. This process is more expensive than granular pavement reconstruction
