Abstract (en)
[origin: EP2623670A2] The track structure (1) has sub-cast layer (3) made of self-compacting concrete, which is formed between support layer (4) and prefabricated panels (2) separated by intervening gaps. The V-shaped reinforcing elements (5) are projected from underside of panels. The bar-shaped reinforcing elements (7,7') are extended in longitudinal direction of panel. The reinforcing elements are embedded in sub-cast layer in longitudinal direction of panel, so that track support plate is formed by attaching sub-cast layer together with panels.
