Embodiment Construction

[0034]In a preferred exemplary embodiment according to FIG. 1, the reinforcement layer 5 is arranged between the first elastic layer 3 and the second elastic layer 4 of the tie foundation 1. Here, the second elastic layer 4 forms the lower exterior surface 6 of the tie foundation 1, i.e. in the operating position facing away from the railway tie and / or opposite thereto. On the opposite side, i.e. the one pointing towards the railway tie 2 in the operational position, the tie foundation 1 is provided with the connection layer 7, which in the exemplary embodiment shown here is embedded in the first elastic layer 3. The connecting layer 7 forms a spatially expanded grid made from threads 9. The clear spaces 8 are formed between the threads 9, into which the material of the railway tie can penetrate in the sense of a form-fitting, material-fitting, or fabric-fitting connection. In order to fasten it to the first layer 3, the connection layer 7 is embedded by approx. 40% of its thickne...
