RAIL TRACK PAVING Russian patent published in 2006 - IPC E01C9/04 E01B2/00 E01B19/00 

FIELD: pavings for railroad level-crossings.

SUBSTANCE: rail track paving comprises inner paving members arranged between both rails and having flat top surfaces and outer paving members adjoining rails and also having flat top surfaces. Paving members are located over several serially laid sleepers in longitudinal direction and spaced from the sleepers and from bed arranged over the sleepers. Inner paving member weights and loads applied to inner paving members are transmitted only to both rails through support extensions inserted in side rail depressions. Paving members are installed on load-bearing members extending in sleeper directions and span space defined by sleepers. Each load-bearing member consists of two supporting and positioning shoes connected with each other by elongated ties. The shoes have dimensions in longitudinal rail direction of not more than space between rail fasteners located on serially laid sleepers. The shoes also comprise above support extensions formed on shoe surfaces facing rails and adapted to be inserted in above side rail depressions. The shoes are positioned along load-bearing member tie length aligned with rail track dimension in sleeper direction to insert the support extensions in adjacent depression of corresponding rail. Paving members located on load-bearing members are restricted from side displacement relatively the shoes by profiled engaging means. Paving members located between the rails and partly closing the shoes in sleeper direction reach groove for flange edge receiving. Outer paving members are located near the rails.

EFFECT: possibility to use the paving with rail track having variable distances between sleepers.
