Beschreibung
Zusammenfassung:	Photocatalytic composition for application to bituminous road surfaces for the abatement of atmospheric pollutants, wherein the photocatalytic composition is in the form of an aqueous dispersion and comprises less than 5% by weight of a photocatalyst, relative to the weight of the photocatalytic composition, less than 10% by weight of an organic resin, relative to the weight of the photocatalytic composition, water and optionally further additives and wherein the photocatalytic composition is applied in an amount and in a manner suitable that upon drying, a layer comprising the photocatalyst and the resin is formed on and/or in the road surface, wherein the layer is adhering to and at least partially covering the surface, but not substantially completely filling the air voids of the surface.
