Council's Road Maintenance Programs is based on a three-stage approach in order to maximise the life span of each street/road, and the total level of expenditure on the road network.
Based on the results of condition assessment, a road surface will be subjected to rejuvenation treatments as a low cost method to extend the life span of the roads surface. After multiple treatments, the road surface will age to a point where rejuvenation will no longer take effect. At this point, Council will overlay a new road surface over the old existing surface and begin the cycle of rejuvenation treatments again. Following multiple resurfacing and many years of road use, eventually the road base course will deteriorate to a point where it will require reconstruction and a new road surface. At this point the entire cycle will begin again.
Through this three-stage approach, Council is able to greatly extend the road lifespan across the City of Prospect’s entire road network and minimise the total road maintenance cost per annum.
Low cost maintenance of road surface will be carried out through surface rejuvenation treatments as required, to maximise the usable lifespan of a road where possible based on condition assessments. If the surface is beyond rejuvenation treatment repair as per condition assessments, the road will be resurfaced to further extend its lifespan. If resurfacing the road is not an option due to the failure of the road base based on condition assessments, the road will be reconstructed from the base to the surface.
The following arterial road surfaces are maintained by Department of Planning, Transport and Infrastructure (DPTI):
- Churchill Road
- Fitzroy Terrace
- Hampstead Road
- Main North Road
- Nottage Terrace
- Prospect Road
- Regency Road
- Torrens Road
If you have a complaint or query about the surface condition of these arterialplease contact DPTI at www.dpti.sa.gov.au or phone 1800 018 313.

Road Rejuvenation Program
One of the major components of an asphalt surface is bitumen. As bitumen ages, progressive chemical changes occur which result in the loss of volatile fractions from the bitumen. Gradual hardening of bitumen follows the natural effects of ageing, temperature and oxidation. This renders the bitumen hard and brittle which leads to surface failures and ravelling.
In order to minimise this effect and extend the useful life of the road surface, rejuvenation of the bitumen is required to increase flexibility and longevity of the surface. Surface enrichment/Rejuvenation is essentially the replacement of bitumen lost due to pavement weathering over time.
Rejuvenation is achieved through the application of appropriate hydrocarbons contained within specifically formulated bitumen emulsions which results in the deposit of the fresh bitumen over the top of the old binder.
The rejuvenation treatment process increases the useful life of the road surface at a fraction of the cost of surface renewal. Flexibility, surface texture and Aesthetics are improved after treatment.
The Infrastructure and Assets Department continually undertake condition assessments to devise appropriate Rejuvenation programs annually to prolong the lifespan of our road network.
