Title
(EN) RESILIENT SOLE AND METHOD FOR MANUFACTURING SAME
(FR) SEMELLE ÉLASTIQUE ET SA METHODE DE FABRICATION
Abstract
(EN) Resilient sole 1 which is attached to a concrete layer (2) or which is positioned between a concrete layer (2) and ballast (3), and which is formed by a layer (4) of recycled rubber, in the revulcanised state after devulcanisation, and a layer (5) of structured fibres which is arranged so as to be in contact with the rubber layer, the fibres being partially impregnated in the rubber layer and having a free thickness (8) of structured fibres, assembly comprising the sole and method for manufacturing same.
(FR) Semelle élastique 1 fixée à une couche de béton (2) ou interposée entre une couche de béton (2) et un ballast (3), qui est constituée d'une couche de caoutchouc recyclé (4), à l'état revulcanisé après dévulcanisation, et d'une couche de fibres structurées (5), disposée en contact avec la couche de caoutchouc, lesdites fibres étant partiellement imprégnées dans ladite couche de caoutchouc et présentant une épaisseur de fibres structurées libre (8), ensemble comprenant la semelle et méthode de fabrication de celle-ci.
