"In one test, paving material using photocatalytic cement was used to cover the asphalt surface of a 230-meter- long stretch of road outside Milan with an average traffic flow of 1,000 vehicles per hour. Tests showed a reduction in nitrogen oxides at street level of about 60 percent, according to Italcementi."
