Abstract: The preservation of suitable air quality standards has been up to now pursued through interventions directed to the reduction of polluting emissions: traffic regulation and improvements in vehicles and fuels.
Photocatalytic materials represent a new resource of opposition to air pollution, favouring the pollutants degradation. Possible applications of these eco-active materials in urban contexts are various: paints and cements, made photocatalytic thanks to the addition of titanium dioxide, are suitable for the application on a high number of different surfaces.
The road surface is, both for size and distribution, one of the primary elements constituting urban tissue, therefore different kinds of photocatalytic road pavements are actually tested: cementitious, bituminous and combined.
This paper especially refers to a kind of pavement combining the characteristics of a traditional bituminous pavement with the effective photocatalytic action of cementitious mortar and titanium dioxide. The Authors present the results of an experimental study concerning the photocatalytic mortar and its application on an asphalt concrete layer.
