1. Recycled Roads to Zero Waste
Business Case

2. Background
High % of waste starts with households and Councils collect it
Quarry resources are finite and running out in many areas
increasing VicRoads activity in using recycled materials in pavements: new standards (15-30% glass/brick)
increasing LG activity (4 mt pa G/B/C; Accord)
Governance Group > VR, SV, MAV, Eco-Buy, Swinburne, PSF, Councils
Specification testing (15% & 30%), workshops
Demonstration Trials:
Manningham (255m footpath, 22 tonnes 20%)
Port Phillip (100m glass)
Brimbank (375m road, 155 tonnes
Surf Coast (800m road, 900 tonnes recycled concrete)
Bayside

3. Bayside City Council Recycled Roads to Zero Waste
2010/2011 Capital Works Program
$ 1.3M Residential Concrete Footpath Reconstruction Program
$ 600,000 Residential Asphalt Footpath Reconstruction Program
$ 550,000 Road Reconstruction Program
$ 400,000 Shopping Centre Footpath Reconstruction projects

4. Footpath trial – Ludstone Street, Hampton
Project completed in April 2011
100m of concrete footpath reconstruction
30% of <5mm diameter glass blend in Class 3 crushed concrete base
7.6 tonnes of non-recyclable glass
Compacted very well under standard plate compaction

5. Road reconstruction trial – Tramway Parade, Beaumaris
Project in construction, programmed for completion mid June 2011
Project cost $355,000
270m length of road of which 36% was full depth pavement reconstruction
15% of <5mm diameter glass blend in Class 3 crushed concrete sub-base
41 tonnes of non-recyclable glass
Easily placed and specified compaction achieved as if using Class 3 crushed rock or concrete
High consistency in mix

6. Bayside Observations Performance during construction
Easy to place and compact, high compaction achieved with standard processes
No noticeable difference in appearance (particularly road)
Contractors commented no issues with using this material
Long term performance
Projects recently undertaken, long term durability and serviceability of pavement to be monitored and assessed

7. Bayside Future plans
Trials were considered successful during construction
Long term performance to be assessed with review of other trial projects
Propose to use in future projects, pending costing and review of completed trial projects

8. What next? 2012: asked Councils to commit: low response
multi-functional: engineering, works, procurement, contracts (and contractor choice)
senior management not involved
timing issues
2013: survey of 30 Councils
97% use recycled if no cost difference and supply OK
New procurement guidelines evolving: VR/sustainability
Business case would be advantageous

9. Business case
Reports of 70% increase in price of quarry materials in Sydney: sourced from 200km
Project Group: Sustainability Victoria (funding), MAV, VicRoads (netbalance)
Report: ‘Recycled materials in pavement construction’

10. ‘Recycled materials in pavement construction’
Key points
Growing development threat to virgin supplies: over time will become more difficult to obtain
Recycled materials perform as well as virgin materials
Recycled materials can be cost competitive
Proximity to recycled source is key determinant
(up to 45km better; up to 85 km competitive)
Significant regional differences (see maps)
VicRoads specifications are very important

11. ‘Recycled materials in pavement construction’
Benefits of using recycled materials
Reduced impact on the environment
Reduced waste to landfill
Reduced energy to produce pavement materials
Reduced land use conflict
Improved security of supply
Reduce risk to Council
Recycled materials can be cheaper

12. ‘Recycled materials in pavement construction’
Recommendations for Councils:
Commit to use of recycled material which meets specifications and cost (Council choice)
Identify current availability of recycled material and potential barriers in your Council
Require contractors to report on their use of RM
Develop a strategy to increase use of recycled content: discuss with contractors
Include VicRoads spec 820 and 821 for road design

13. Choice Option to use recycled materials OR
Where there is supply at cost competitive rates, Council preference is for recycled materials in blends of 15%-30%

14. Next steps
May 2014: MAV presentations to regional meetings of CEOs and Mayors. Seek support for:
LG strategic direction: increased use (preference)
VicRoads future direction
Good practice policy and contract management guidelines (give preference)
Local recycling to be maximised (work with local WMG)
Inclusion in Council plans
