Abstract

A continuous running track to be supported by a bridge structure includes at least two bridge segments, a load-bearing structure to support the segments, a continuous slab extending from one end to the other end of the bridge and resting on the segments, an antifriction layer beneath the continuous slab, acting as an interface between the upper surface of the segment and the lower surface of the continuous slab and defining a slip plane for the continuous slab, and a crossing plate beneath the continuous slab, extending from one end of a segment to an end of a directly adjacent segment. At least one anti-lift device to be fixed to a segment is capable of limiting a movement of the slab in a direction perpendicular to the slip plane while providing for freedom of movement of the slab on the slip plane.
