Pavement rehabilitation - completed projects

This project continued our use of more environmentally sustainable products by undertaking a recycling process with foam bitumen stabilisation where no materials are wasted and the new road laid is made of recycled materials. During the first stage of works between Macarthur Avenue and Mouat Street, the following benefits were seen:

• More than 6,000 tonnes of existing pavement material recycled on site
• New imported materials to site was reduced by 69%
• 20 weeks reduction of traffic impacts for the community (80% faster than using traditional techniques)
• A reduction of greenhouse gas emissions (measured in CO2 equivalents) by 61%.
• 40% savings in project costs and a road that is built to last for the next 2 decades.

Macarthur Avenue to Mouat Street

Using standard methods of pavement rehabilitation, this project would have taken approximately 26 weeks to complete. However, using foam bitumen stabilisation the project took just 6 weeks.

Repairs have been completed along David Walsh Avenue in Forde and Isabella Drive to create a smooth, more resilient road for safer travel and better driveability.

These road repairs were significant and included:

• removal of existing road pavement
• repairs to kerbing and stormwater drains where required
• placement of new road pavement
• line marking.

This project continued our use of more environmentally sustainable products by undertaking a recycling process with foam bitumen stabilisation where no materials are wasted and the new road laid is made of recycled materials.

This project was funded under the Australian Government’s Roads to Recovery program.

Project description

Tarra Place and Jabanungga Avenue were constructed as part of Ngunnawal Estate Development 3B Stage 2 in 1994. The road pavement has repeatedly and rapidly deteriorated from water saturation in three areas at the intersection of Tarra Place and Jabanungga Crescent since around 2014.

A range of investigations have taken place including site visits, aerial mapping, CCTV inspections, visual inspections with a ground penetrating radar to locate existing services and geotechnical investigations to determine the extent of the damage.

Investigations to determine the source of the underground water were inconclusive. However, it was determined the water was not running water from existing utility services and was existing pooled water which could be related to a rising water table following a rainfall event. Through the investigations it was determined pavement rehabilitation and upgrades to existing drainage infrastructure are the necessary treatments.

Stage 2

The additional road repairs identified for the intersection of Arrabri Street, Warabin Crescent and Jabanungga Avenue are complete.

These works included repairs to the damaged road, installation of additional underground drainage and an asphalt overlay.

2 km on both sides of the road, from the Mill Post Road intersection to the ACT/NSW border.

8 km of the Monaro Highway was rehabilitated, from the Jerrabomberra Creek intersection at Hindmarsh Drive to David Warren Road.

This project was funded under the Australian Government’s Roads to Recovery program.

1.7 kilometres of road pavement was rehabilitated between Tillyard Drive and Owen Dixon Drive.

This project was funded under the Australian Government’s Roads to Recovery program.

Work to rehabilitate Sulwood Drive between Athllon Drive and the Mannheim Street intersection and from the Mannheim Street intersection to the Tuggeranong Parkway has been completed.

Work to rehabilitate the road pavement along Sawmill Crescent in Hume has been completed.
