Abstract (en)
[origin: EP0751257A2] The rubber Pan (6) has an asymmetry that varies the rigidities on the sides directly in proportion to the stresses applied by the concrete block (4) due to the wheel-rail interaction. The asymmetrical variation can be achieved by decreasing the number of interspaces (8) between the ridges (7). The pan subject of the invention is applicable to double-block sleepers without a spacing bar in order to prevent pitching of the concrete block (4) and therefore gage widening of rails. <IMAGE> <IMAGE>
