Motorists on the Murray Valley Hwy in Cobram will be the first in Victoria to drive on a new road compound.
A world-first toner and rubber modified spray binder that makes use of waste items was used in a trial to seal the highway on February 15.
The product Tonerseal, which is made from a combination of used car tyres and toner from recycled printer cartridges, has been produced by Downer and was used by VicRoads.
Downer Road Services executive general manager Dante Cremasco said Tonerseal was a high performance recycled spray seal product using waste items such as toner from printer cartridges and crumb rubber from used tyres that would typically be stockpiled or sent to landfill.
‘‘Compared to unmodified binders, Tonerseal is expected to improve stone/aggregate adhesion to the binder seal, extending the life of the seal and reducing damage to road vehicles,’’ Mr Cremasco said.
‘‘Its improved flexibility and elastic properties is expected to improve water proofing, and provide further benefits in handling high volumes of traffic and hot conditions.’’
Every 1km of road lane paved with the new material uses about 6400 toner cartridges and about 145 car tyres.
VicRoads regional director Nicki Kyriakou said VicRoads supported the innovative approach to road treatments. ‘‘We will continue to work with Downer to monitor this section of road. There will be dedicated assessments of the road and how the product performs,’’ Ms Kyriakou said.
The project will be delivered on the Murray Valley Hwy, Cobram, between Campbell Rd and Oak St, covering about 2km.
Users of the highway did not have to wait long, as Mr Cremasco said the most difficult part of sealing a road was closing it off to traffic. The actual spraying and drying was a quick process, he said.
