ABSTRACT:
The present invention relates to a process for coloring or dyeing a material formed essentially from a substrate impregnated with bitumen, said method being characterized in that a colored composition is applied, in particular a pigmented composition, to the substrate before the impregnation of the latter by the bitumen. It also concerns the material thus obtained, characterized by a color gradient between the surface and the inside of the substrate, the color intensity decreasing continuously and practically regularly from the surface.
