Abstract:	Im Rahmen dieses Forschungsvorhabens werden TiO2-haltige Gesteinskörnungen hergestellt und hinsichtlich der Festigkeit, des Polier- und Verschleißwiderstands sowie der Dauerhaftigkeit der photokatalytischen Eigenschaften optimiert. Sie werden auf die Fahrbahnoberfläche aufgebracht, um das durch die Abgase des Kraftfahrzeugs emittierte NOx möglichst schnell und effektiv abzubauen. Als Ergebnis kann festgestellt werden, dass mit dem erarbeiteten Verfahren ein langfristiger NOx-Abbau auf Asphaltstraßen durch den Einsatz des TiO2 mit photokatalytischen Eigenschaften erzielbar ist. Damit ist ein wichtiger Schritt hin zur Herstellung des umweltfreundlichen Straßenbelags mit photokatalytischem Stickstoffdioxidabbau vollbracht. Environment-friendly road surface with photocatalytic decomposition of nitrogen dioxide In the scope of this research project, variants of TiO2-containing aggregates were produced and optimized on their strength, polishing resistance, wearing resistance and the durability of the photocatalytic performance. The aggregates are spread on the road surface in order to decompose the emitted NOx in the exhaust gas of the vehicles as quickly and effectively as possible. From the results, it can be ascertained that a durable NOx degradation is achievable by using the TiO2 in the spreading materials on asphalt road surface following the developed procedure. Through this, an important step of building environment-friendly road surface with NOx elimination is taken.
