The invention relates to a fixed road for rail-bound vehicles on a bridge, wherein the fixed road consists of a bridge superstructure slab, a support slab covering said bridge superstructure slab and comprising longitudinal humps and stoppers and a ballast slab comprising clearances, on which the rails are arranged with fasteners. The invention is based on the object of developing a structure which requires simpler longitudinal reinforcement and reduced shuttering and manufacturing expenditure and makes possible the manufacture of longer ballast slabs. According to the invention, this is achieved in that the support slab (1) comprising the longitudinal depression (7) comprises only one stopper (5) at the height of the middle of the ballast slab (8) to be arranged above and the longitudinal depression (7) of the support slab (1) in this region is interrupted by the stopper (5) over a length of 60 to 100 cm and the ballast slab (8) comprises a longitudinal rib (4), which in its middle region is interrupted by means of a clearance (6) over a length of 65 cm to 105 cm in which the stopper (5) of the support slab (1) positively engages. |
