Central Goldfields Shire has received a National Award for Excellence.
Presented on 26 July, the AustStab – Pavement Recycling and Stablisation Association Award - Excellence in Research or Education category - was presented to Central Goldfields Shire.
The Awards are sponsored by Caterpillar and are open to any individuals and Australian private and public organisations working in the area of pavement recycling and stabilisation.
The award was presented for the Unsealed Roads Treatment Trial Project currently underway on Possum Gully Road, Adelaide Lead.
Central Goldfields Shire Council Mayor Cr Geoff Lovett said the award was a wonderful achievement for our engineering team.
“It’s wonderful to see the efforts of our staff acknowledged publicly and to see us take out a national award for excellence is due recognition that we are a small shire delivering great outcomes for our community.
“It’s 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 1200kms 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.
