Creating Roads From Sand and Bacteria Instead of Oil

Improving America’s infrastructure has been a major priority for the Obama Administration, with a lot of money going into repairing the country’s roads and bridges. The problem is that currently most roads are constructed from asphalt, a material made from oil that increases national fossil fuel usage, is expensive, and is damaging to the environment. However designers Thomas Kosbau and Andrew Wetzler have come with a plan for a greener alternative — a “biologically treated and processed paving material” that uses a common microbe to transform loose grains of stand into stable, road-worthy sandstone.
