That is a lot of pavement lying around out there doing nothing but waiting to be driven over. What if all those miles of road were actively doing something rather than just lying there? If only the roads were paved with “air-purifying concrete.”

One of the pollutants spewed into the atmosphere by cars and trucks is nitrogen oxide (NOx), which is responsible for acid rain and smog. Researchers in the Netherlands recently concluded the first outdoor highway test of a specially designed type of concrete that works to remove NOx from the air. The new road surface material “reduces the concentration of nitrogen oxides (NOx) by 25 to 45 per cent.”
