Self-Cleaning Roads!

The University of Eindhoven  in the Netherlands found a way to create roads that clean themselves and the air around it.
According to the university, the normal road surface is infused with some sort of material that can decrease the NOx in the air. The NOx is captured by some Titanium Dioxide particles in the pavement and then some sort of photocatalytic material converts the NOx to nitrate. Said nitrate is then washed away when it rains. The material in the asphalt also breaks down algae and dirt somehow to keep the road clean.
Not bad research, wondering how expensive this would be on all the tax payers out there. Although these roads would be a wonderful addition to high pollution areas such as California...
