CA 2284576

The invention provides an elastomeric rail pad (1) of generally rectangular plan configuration, the pad having an upper face (2) adapted to underlie the lower face of a rail, and a lower face (5) adapted to overlie a concrete rail foundation member characterised in that the pad includes a reinforcement means (13) which is generally parallel to its mean plane and extends at least between dispositions associated with generally opposing corners of the generally rectangular pad (1), said reinforcing means (13) having a tensile strength such as to resist, in use of the pad (1), forces from traffic passing across the rail disposed therabove otherwise tending to stretch the pad (1) in the mean plane thereof.

L'invention concerne une semelle de rail élastique (1) à configuration plane généralement rectangulaire, la semelle présentant une face supérieure (2) conçue pour soutenir la face inférieure d'un rail, et une face inférieure (5) conçue pour recouvrir un élément de fondation de rail en béton. La semelle de rail élastique de l'invention est caractérisée en ce que la semelle comprend un dispositif de renfort (13), généralement parallèle à son plan médian et qui s'étend au moins entre des dispositions associées à des coins généralement opposés de la semelle (1) généralement rectangulaire, ledit dispositif de renfort (13) présentant une résistance à la rupture le rendant capable de supporter, lors de l'utilisation de la semelle (1), les forces provoquées par le passage de trafic sur les rails disposés sur cette dernière, et tendant sinon à étirer la semelle (1) dans le sens de son plan médian.
