The superstructure (2) of a carriageway is embodied in a multi-layer manner and comprises, as the surface and first layer (3), a hardened compound consisting of glass particles, an organic adhesive, and a polyurethane adhesive. The glass particles are a mixture of glass beads and broken glass. The light-positive property of the glass particles of the compound enables the colour of the adhesive to be continuously transmitted from glass particle to glass particle up to the surface, such that the colour can also be seen when the glass particles are worn down or the adhesive is soiled or becomes turbid on the surface side. In this way, permanent colour stability is ensured even when the surface is worn down. The surface thus maintains the aesthetically pleasing or indicative colour thereof. |
