The possibility to use the additive of nano-disperse titanium dioxide in the structural form of anatase, obtained by the ultra-sound dispersion of pigment powder in water medium of sodium oleate, as a phto-catalytic pavement on the concrete surface ensuring its high self-cleaning capacity is theoretically and experimentally substantiated. Theoretical and experimental assessment of the photo-catalytic activity of the additive containing nano-particles TiO2 is made. The dependences of changing the intensity of coloring of organic pigments, methylene red and methylene blue, on the duration of the ultraviolet radiation exposure are obtained. The established change in optical density of the coating from 0.328 to 0.093 (by 3.5 times) demonstrates the decrease in the concentration of the organic pigment on the substrate of the additive of nano-dispersed titanium dioxide confirming the intensity
of the photocatalytic reaction due to the high oxidizing capacity of the medium formed on the surface of particles TiO2 under the impact of UV light.
