Abstract

Il est décrit un élément moulé (1) en caoutchouc régénéré vulcanisé, renfermant des copeaux (2) de caoutchouc régénéré vulcanisé, agglomérés entre eux au moyen d'un liant durcissant, et dont les formes, les dimensions et les positions mutuelles sont choisies de telle façon que l'élément moulé présente des espaces creux reliés entre eux et vers l'extérieur. Ces éléments moulés conviennent, notamment sous forme de plaques, comme agents de préparation du sol, par exemple, pour la fixation et comme infrastructure de surfaces du sol soumises à de fortes contraintes, par exemple, comme sous-sol pour des stades, des pistes de terrains de sport, comme infrastructure de voies ferrées ou comme éléments de passages à cabrouets. En raison de leur bonnes propriétés de résistance mécanique et de leur faible masse spécifique, conjointement avec leur bonne étanchéité à l'eau, les éléments moulés conformes à l'invention sont également bien appropriés comme plaques de revêtement gazonné ou, en raison de leurs propriétés d'isolation phonique, comme éléments de construction pour murs anti-bruit.
