The NO -cleaning paving structure of the present invention comprises a concrete base layer , a paving layer and a surface layer as illustrated in FIG. . The surface layer comprises 100 parts by weight of cement, 5-50 parts by weight of titanium oxide powder and 100-700 parts by weight of aggregate, by which the surface layer on the paving layer can be provided with an NO -cleaning action and an excellent durability. In addition, pozzolan materials, particularly a blast furnace slag, or adsorbing materials can be added to the surface layer. The paving layer comprises an asphalt paving or a concrete paving , both of which may include the used paving layers. It is preferable that the asphalt paving is porous and the surface thereof has an unevenness. Additionally, it is preferable that the thickness of the surface layer is 1-300 mm for the concrete paving and 2-15 mm for the asphalt paving.
