Description

  The present invention provides a pavement structure outside a track gauge provided between the outside of the rail and the asphalt paved road outside the track gauge, and outside the track gauge constituting the road surface outside the track gauge. It relates to the paving method.

  Conventionally, the applicant did not remove the sleeper of the track at the railroad crossing, but mounted a wide plate-like member (hereinafter referred to as “track pavement member”) on the sleeper. A track pavement structure (hereinafter referred to as “pavement member detachable level crossing”) in which the upper surface of the pavement member is used as a road for a level crossing is proposed (see Patent Document 1).

  This pavement member detachable level crossing has a simple structure, so both material costs and construction costs are low, and the roadbed can be removed if the track pavement member is removed even during crushed stone crushing work by MTT (multiple tie tamper). Therefore, there is an advantage that work can be performed continuously with the track before and after the railroad crossing, and efficient mechanized track maintenance work can be performed.

However, in the conventional pavement member detachable level crossing described above, there is a thin plate-like pavement insulating member or gap between the off-gauge track pavement member constituting the road surface outside the gauge of the track and the asphalt pavement road portion. Since only the spacer member etc. is arranged, the asphalt pavement road part which touches the pavement insulation member and becomes the boundary with the level crossing is worn away by the running of a large automobile such as a dump truck, and a step is generated. When driving an automobile, the tire may impact the off-gauge track pavement member horizontally in the direction towards the rail. There has been a problem that an excessive force acts on a bolt or the like for attaching the member to cause deformation or breakage.
