Australia tested the world's first 'green road'

Scientists at the University of New South Wales in Australia are testing the construction of the world's first "green road" in Sydney.

This is a quite busy route leading to Sydney International Airport.

Geopolymer is described as "a sustainable blend between concrete and recycled waste".(Source: BFT International).

The material to create this particular path is industrial waste from this steel industry and coal-fired power plants in this Oceania country, namely fly ash - a kind of pozzolan active mineral used additive for manufacturing high strength concrete and blast furnace slag.

This mixture of geopolymer materials is described as "a sustainable blend of concrete and recycled waste" , with a great promise to reduce carbon emissions globally. A 30m long road is being tested for this technology, before being applied on the entire route.

Scientists have installed 9 sub-surface sensors on this road to evaluate the project's performance.

Mayor Sydney, Clover Moore, said: "Projects like this geopolymer test can produce new products, which bring significant results in reducing carbon emissions. Local governments bear responsibility for road management in the area, so if we buy more sustainable materials with the environment, we can combat climate change and provide quality infrastructure for the community. my copper ".

Professor Stephen Foster - Dean of the University of New South Wales Department of Civil Engineering and Environment, said: "Concrete contributes 7% of all greenhouse gas emissions, thus the This test will help to accelerate the change in the construction industry, and research on geopolymer has been around since the 1990s, but only now has it begun to be commercialized. This experiment is important because we need demonstration projects to accurately evaluate the performance of geopolymer over time, so that it can be replicated later. "

According to Mr. Foster, the process of tracking road performance will be done for up to 5 years, while much of the data collected during the first 3 to 12 months of the test will be used to confirm the Research model and reinforce scientists' beliefs.
