Central Goldfields Shire has received an Award for Excellence.
The Institute of Public Works Engineering Australasia (Victoria Division) awards were announced yesterday, Thursday 10 May.
Central Goldfields Shire was presented with an award in the Innovation – Regional category for the Unsealed Roads Treatment Trial Project on Possum Gully Road, Adelaide Lead.
The Awards recognise excellence in innovation, development, construction and management in public works and the Excellence in Innovation category recognises excellence in the implementation of areas that can be considered exceptional by traditional standards.
Central Goldfields Shire Chief Administrator Noel Harvey said the award was a fantastic achievement.
“Congratulations to our Engineering team – it’s always great when the efforts of our staff are acknowledged publicly and to see us take out a Victorian award for excellence is due recognition that we are a small Shire delivering great outcomes for our community.
“It’s also fantastic to see our staff seeking sustainable and cost-effective ways to improve our unsealed road network into the future.”
The trial project involved treating local gravels from our Dunolly and Daisy Hill quarry with difference additives to test their performance as a road surface for unsealed roads.
The Shire has a total of 1300kms of roads in our municipality, 750km of which are unsealed, making them susceptible to weather, varying traffic volumes and the performance of gravels.
In an effort to improve the performance of our local gravels on unsealed roads, our engineering team embarked on a trial project in December 2016 to see if some of our marginal local gravels could be enhanced for more effective use.
The gravel surface on a 2,500 metre section of Possum Gully Road was treated with additives such as foam bitumen, enzyme, cement, polymer, poly citrus, additional clay and bluestone rock.
Ongoing testing and monitoring will be carried out over a two year period to determine which as the best performing and economically viable treatments.
The trial projects aims to better understand how our local gravels can be utilised more effective and efficiently with limited resources to find more sustainable ways to improving the performance of our local unsealed roads into the future.
