本发明涉及一种铁路上层结构，其包括作为轨道载体系统的连续支撑的轨道床垫（10）。 轨道床垫（10）由具有聚氨酯粘合的橡胶回收材料或具有特殊规格的聚氨酯组成，并且具有横向于垫平面延伸的孔，使得静态床模块的特定弹性效应在0.005至 0.08 N / mm2，动床数模量在0.02〜0.1N / mm2之间。

Railway track with a track bed mat (10) as a continuous support of a rail carrier system. The track bed mat (10) is made of either rubber recycling material with polyurethane binding, or polyurethane special specification, and is transversely perforated for Matt level, so that a certain springiness with static bedding modulus from 0.005 to 0.08 N / mm2 and with dynamic bedding modulus between 0 , 02 is to 0.1N / mm2 achieved.
