Abstract

L'invention concerne une superstructure ferroviaire comportant un tapis sous ballast (10) formant une base continue d'un système de support de voie. Le tapis sous ballast (10) est constitué soit d'un matériau recyclé en caoutchouc contenant un liant polyuréthane, soit d'un polyuréthane répondant à des spécifications spéciales, et est perforé transversalement au plan du tapis, de sorte que l'on obtienne une élasticité déterminée caractérisée par un module de réaction du sol statique compris entre 0,005 et 0,08 N/m² et un module de réaction du sol dynamique compris entre 0,02 N/m² et 0,1 N/m².
