Undertaken by Newpave in January and February 2018, the project involved complete resurfacing of the Mooney Mooney Creek Bridge – one of the most heavily trafficked bridges in Australia.
It was the first time since the bridge’s construction in 1986 that whole thickness of asphaltic concrete was replaced. Newpave paved an intermediate course with speciality R127 bridge mix and a wearing course with R119 open graded asphalt.
The project was technically and logistically challenging. When paving the intermediate course, each shift consisted of:
- Set up of approximately 5 km of traffic control
- Profiling to the concrete bridge deck with a fine drum mill
- Drying and suction sweeping the concrete surface
- Surveying the height of the concrete
- Spray seal
- Paving to levels determined by the survey, with computerised level control
- Compaction of the asphalt with non-vibratory, oscillating rollers
- Line marking
- Surveying the height of the of the intermediate course
- Pack up and reopening to traffic
For the wearing course, each carriageway (three lanes and 480 m length) of the bridge was paved in a single shift.
The end-result was a great success. The surface is now stronger, safer and longer lasting, and the tens of thousands of motorists who use the bridge daily can enjoy the better ride.
