PROBLEM TO BE SOLVED: To provide a method for controlling clouding of pavement using decolorized asphalt making it possible to easily maintain the appearance of the pavement created by the color of aggregate, by easily and effectively controlling clouding of the surface of the pavement without using large-scale machinery or devices. SOLUTION: The method controls clouding of the surface of natural-colored pavement 13 formed by laying an asphalt mixture obtained by admixing decolorized asphalt 11 and aggregate 12. A solution containing D-limonene is applied to the surface as a solvent for dissolving the decolorized asphalt covering the surface of the natural-colored pavement 13, and then the decolorized asphalt 11 is isolated from the surface of the pavement 13 by brushing and washed away using a washing machine that utilizes the force of water, to remove the decolorized asphalt 11 on the surface.
