The design, construction and maintenance of roads will face a number of challenges in the coming decades.

Photocatalytic air cleaning is based on the use of titanium dioxide in building materials – for example on roads. This new technique has the potential for removing nitrogen oxides (NOx) and volatile organic compounds(VOCs), as well as reducing concentrations of toxic and irritating ozone from polluted air.

The possibilities for its application have been researched in Japan, there are some applications in Europe, (Belgium, Italy, France ,and the Netherlands), but it is obvious that there is a need for both additional research and use of this technology in the building of ‘clean roads’.
