The invention relates to an elastomer support (10) for a support device (9) for cantilevered segments of an expansion joint in a roadway, especially of bridges with an elastomer element, whereby several elastomer layers (18), at least partially separated by reinforcing elements (17) are positioned in the direction of the main load of the elastomer support (10) and have a thickness (23) of only between 1 % and 20 % of the width dimension perpendicular thereto, preferably between 2mm and 10mm.

L'invention concerne un support d'élastomère (10) d'un dispositif d'appui (9) destiné aux lamelles d'un joint de dilatation placé dans une chaussée, notamment sur un pont, ce support comportant un élément d'élastomère. Plusieurs couches d'élastomère (18), séparées au moins partiellement les unes des autres par des éléments d'armature (17), sont placées dans le sens principal de charge du support d'élastomère (10). L'épaisseur (23) de ces couches d'élastomère a seulement une valeur comprise entre 1 % et 20 % de la largeur mesurée verticalement par rapport à cette épaisseur et est comprise, de préférence, entre 2 mm et 10 mm.
