Road surface purifies air by removing nitrogen oxides (NOx)

Road surfaces can make a big contribution to local air purity. This conclusion can be drawn from the first test results on a road surface of air purifying concrete. This material reduces the concentration of nitrogen oxides (NOx) by 25 to 45 per cent, said prof. Jos Brouwers in his inaugural lecture last Friday.
