Sandstone Road

If you drive along the road, i believe you'll see black asphalt which is commonly used as road pavement. As the world now moves towards a greener alternative, Thomas Kosbau and Andrew Wetzler have a great alternative to black asphalt which creates a lot of problems.

The winner of Incheon International Design Award which was organized by designboom in collaboration with Incheon metropolitan city has created road pavement made from sand and microbes. The microbes are used to alter the properties of loose sand and turn it into a stabilized sandstone. The result is a pavement material that is greener and, quoting the designer's own words "mitigating the harmful effect of asphalt."

All the materials and pictures are taken from designboom site.
