Pat Shingleton: "Paving the Way..."
As D.P.W. crews are filling potholes, pavement replacement may be further considered in the future-for another reason. The Huffington Post reports that in the Netherlands, a special pavement is purfying the air. Titanium oxide removes pollutants from the air and researchers from Eidenhoven University of Technology recorded nitrogen oxide measurements for one year. These emissions from cars and power plants create smog. They found that a stretch of highway sprayed with titanium oxide reduced pollution up to 45% in ideal weather and 19% over the course of a day. The smog-eating concrete was also implemented in Italy and another version was installed in bicycle and parking lanes in Chicago. The expense of the project is limiting more locations.
