![]() ![]() “This binder already meets existing specifications and can be used in any design with a polymer modified binder (PMB) in the asphalt – be it open graded asphalt or others such as stone mastic, gap or dense graded asphalt,” Mr Aloisio said. The Victorian Government’s ecologiQ program helped drive the use of crumb rubber on the M80 and Monash freeways, in line with its ambition to integrate as many recycled materials in transport projects as possible.ĮcologiQ Director Tony Aloisio said these projects were an excellent way to demonstrate the use and viability of crumb rubber. ![]() The equivalent of 662 car tyres were included in the Olexocrumb binder on the M80 Freeway between Sydney Road and Edgars Road.Īs part of the Monash Freeway Upgrade, the project installed 460 tonnes of asphalt containing Olexocrumb on the four lanes on the Eastlink bridge. While crumb rubber has been used for decades on country roads, this marks the first that it has been used as a polymer modified binder in open graded asphalt on a Victorian freeway. The 2021 export ban on whole tyres has further highlighted the need for more end markets. Up to a third end up in landfill or stockpiles. The product’s use has prevented almost a thousand end-of-life tyres ending up in landfill or stockpiles.Īn estimated 56 million passenger tyres reach end-of-life in Australia annually, with a quarter of these from Victoria. Every tonne of binder includes the equivalent of 15 recycled passenger tyres. Olexocrumb is an elastomeric modifier for bitumen in roads that incorporates 10% recycled tyre rubber. The new binder is called Olexocrumb, developed by Puma Energy in Victoria. Upgrades to the M80 and Monash freeways in Melbourne – delivered by Major Road Projects Victoria – have used 66 tonnes of crumb rubber, made of ground up truck tyres, as binder in asphalt. Old truck tyres are being used to upgrade Victoria’s busiest freeways for the first time ever, setting a new standard for the use of recycled materials.
