Research conducted at Â鶹ֱ²¥ of Technology could mean that the next time you drive to the shops you could be driving over the leftovers from someone\u2019s renovation.<\/p>\n
Curtin researchers have been looking at ways of turning construction and demolition (C&D) waste into new roads that will save money, help the environment and provide a superior road for motorists.<\/p>\n
Professor Hamid Nikraz, Curtin\u2019s Head of Civil Engineering, said the technology, already used on parts of the Kwinana Freeway and roads in the Cities of Canning and Gosnells, could provide a cheaper and more environmentally friendly way to construct roads.<\/p>\n
\u201cSince you are reducing the demand for more materials needed to make the roads, you are reducing the rock that needs to be quarried, limiting habitat loss,\u201d he said.<\/p>\n
\u201cBy using fewer resources, substantial environmental and cost savings can be made.<\/p>\n
\u201cLess energy is also used when making roads out of recycled waste, which is also good for the environment.\u201d<\/p>\n
These roads can be made from a number of sources including old concrete pavements and structures, demolished homes and leftover material from construction sites.<\/p>\n
Curtin researchers have been working on the project for two years.<\/p>\n
Curtin Adjunct Professor and City of Canning Project Engineer, Colin Leek, said roads developed using C&D waste were more resilient than those made using traditional newly quarried materials.<\/p>\n
\u201cRoads made in this way are not only cheaper and better for the environment, they are also often superior in quality,\u201d he said.<\/p>\n
\u201cBy using recycled C&D materials we can develop roads with a higher level of stiffness that appear to take longer to crack and degrade than traditional aggregate.<\/p>\n
\u201cYou would not even know you were on one of these roads. Next time you are driving to the supermarket, you may be travelling over an old multi-storey building or leftovers from someone\u2019s renovation.<\/p>\n
\u201cAlthough more research needs to be done on the exact mix of different kinds of material used, this method certainly holds promise.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
