The invention relates to a method of laying a bitumastic simulated paved surface which comprises spreading a layer of hot bitumastic material on a foundation layer, the bitumastic material including a thermoplastic rubber copolymer material, filler and reinforcing fibres, allowing the bitumastic material to cool and set, optionally heating the surface of the bitumastic material as required to soften it for moulding purposes, and imprinting the softened surface with a pattern of grooves to provide the required simulated gaps between the slabs of the required simulated paving. The invention also relates to a layer providing such a simulated paved surface, to a speed control hump having such a surface and to a method of making such a hump.

Méthode d'application d'une surface de pseudo-pavés bitumastiques. La méthode consiste à étendre une couche de matériau bitumastique chaud sur une couche de fondation. Le matériau bitumastique comporte un copolymère de caoutchouc thermoplastique, des éléments de remplissage et des fibres de renforcement qui permettent au matériau bitumastique de refroidir et de durcir. On peut également procéder de la façon suivante : chauffer la surface du matériau bitumastique à la température requise pour la ramollir en vue d'une étape de moulage qui consiste à y imprimer un motif de rainures simulant les espaces entre les dallages de pavés à imiter. La présente invention porte également sur une couche de pseudo-pavés appliquée sur une bosse de décélération et sur une méthode de fabrication d'une telle bosse.
