Paper Abstract

Nowadays, there is an increasing concern about the use of less harmful techniques to the environment, and about road safety in Transportation Engineering. Heterogeneous photocatalysis based on the application of semiconductors materials onto asphalt mixtures is a promising technology because it can mitigate air pollution and road accidents. The functionalized asphalt mixtures with photocatalytic capability can degrade pollutants, such as damaging gases and oil/greases over their surface from specific reactions triggered by sunlight photons, providing significant environmental and social benefits. In this communication, a brief review of photocatalysis applied in asphalt mixtures will be presented.
