description The invention relates to a ballastless track section for a rail vehicle, said section being fastened to a platform (10) and comprising: a prefabricated concrete track slab (20, 120) comprising two stringers (21, 22); a rounded bearing surface (21c, 22c) borne by an underside of each stringer at each longitudinal end and having a curvature of which the centre of curvature is the top of a rail (21b, 22b) borne by the stringer; a prefabricated support pad (30, 130) for supporting each longitudinal end of the slab (20, 120) and comprising at least two support bases (33, 34) for the two stringers of this longitudinal end of the slab, each base (33, 34) comprising at least one shim (33a, 34b) of predetermined thickness supporting said rounded bearing surface (21c, 22c) of the stringer of said slab facing this base. L'invention concerne une section de voie sans ballast pour véhicule ferroviaire destinée à être fixée sur une plateforme (10) comprenant : une dalle (20, 120) de voie préfabriquée en béton comprenant deux longrines (21, 22); un appui arrondi (21c, 22c) porté par une face inférieure de chaque longrine à chaque extrémité longitudinale qui présente une courbure dont le centre de courbure est le sommet d'un rail (21b, 22b) porté par la longrine; un plot (30, 130) de support préfabriqué de chaque extrémité longitudinale de la dalle (20, 120) comprenant au moins deux embases (33, 34) de support des deux longrines de cette extrémité longitudinale de la dalle, chaque embase (33, 34) comprenant au moins une cale (33a, 34a) d'épaisseur prédéterminée supportant ledit appui arrondi (21c, 22c) de la longrine de ladite dalle en regard de cette embase.
