Abstract
A railroad tie having a compact design for a fixed track with an overlay of asphalt of the Getrac A3 construction with a dowel stone which is inserted in a recess and which protrudes downward into engagement with a cavity pocket of the asphalt track. The railroad tie is constructed as a double railroad tie which forms only a narrow gap with the adjacent railroad tie in order to make radial laying (curve) possible and which is provided in the region of the dowel stone on the underside with lateral constrictions so that the cavity pockets can be filled subsequently.

A railroad tie having a compact design for a fixed track with an overlay of asphalt of the Getrac A3 construction, comprising:
- a body having first and second rail-supporting portions and a central portion between said first and second rail-supporting portions, said first and second rail-supporting portions having a width, said central portion having a recess on an underside;
- a dowel stone arranged in said recess on the underside of said central portion of said body and adapted to engage a cavity pocket of the asphalt track,
- said body including lateral constrictions arranged in a region of said dowel stone to provide said central portion with a smaller width than the width of said first and second rail-supporting portions such that ends of the cavity pockets are uncovered.
A railroad tie unit for a fixed track with an overlay of asphalt of the Getrac A3 construction, comprising:
- first and second railroad ties separated from one another by a narrow gap to enable radial laying of rails, each of said first and second railroad ties comprising
- a body having first and second rail-supporting portions and a central portion between said first and second rail-supporting portions, said first and second rail-supporting portions having a width, said central portion having a recess on an underside;
- a dowel stone arranged in said recess on the underside of said central portion of said body and adapted to engage a cavity pocket of the asphalt track,
- said body including lateral constrictions arranged to provide said central portion with a smaller width than the width of said first and second rail-supporting portions such that ends of the cavity pockets are uncovered.
A fixed track of the Getrac A3 construction, comprising:
- a lower supporting layer;
- an asphalt layer arranged above said lower supporting layer, said asphalt layer including a plurality of cavity pockets;
- and
- a plurality of railroad ties separated from one another by narrow gaps, each of said railroad ties comprising
- a body having first and second rail-supporting portions and a central portion between said first and second rail-supporting portions, said first and second rail-supporting portions having a width, said central portion having a recess on an underside;
- a dowel stone arranged in said recess on the underside of said central portion of said body and engaging a respective one of said cavity pockets of said asphalt layer,
- said body including lateral constrictions arranged to provide said central portion with a smaller width than said first and second rail-supporting portions, said central portion having a smaller width than the width of said respective cavity pocket such that ends of said respective cavity pocket are uncovered.
