A method of surface treating workpieces formed of cement, bituminous or other bonding materials to be coated with a cover layer, such as roads, airport and bridge surfaces, and the like, including the steps of roughening the surface to be coated and then cleaning the surface before applying the cover layer, where the roughness depth (RT) corresponds to one-half of the diameter of the largest grain (1) of the surface to be coated or of the cover layer and the width of the undulations of the surface to be coated correspond to the diameter of the largest grain. The undulations can be formed along a single axis or along two axes.
