摘要： A method for restoring and reusing railroad ties and the resulting product are disclosed. According to the method, otherwise spent wooden ties are sorted as to their apparent suitability for providing a core for reuse. Those found unsuitable are discarded, while those found to be suitable are milled or trimmed about their dimensions to define a suitable core. That core is banded about a transverse perimeter and then submitted to a reaction injection molding process by which urethane or other suitable polymers impregnate the various voids, holes and cracks in the core, bond with the bands, and define a finish unit having the overall size and configuration of previously known railroad ties. The encapsulated product is then capped or plugged at the ends to ensure that the resulting product is impervious to penetration by the environment.

摘要： A laminated wood and encapsulated railroad tie structure and its associated method of manufacture. A wood core of laminated wood slats is inserted into an extruded sleeve of scrap tire rubber and polyurethane. A urethane adhesive laminates the wood slats together and serves as a lubricant and bonding agent for placement and secured engagement of the sleeve about the core. End caps are securely engaged at each end of the composite sleeve, being secured to both the wood or other natural fiber core and sleeve. Longitudinal grooves or slots for engagement with a railroad bed characterize the bottom and side surfaces of the sleeve. The core may be provided with bores and grooves to receive sensors and conductors interconnected with a processor and transponder maintained in an end cap. The end case also maintains a photovoltaic device and power source for the active elements of the railroad tie structure. The core may also be manufactured of a wood or other natural fiber giving the core a desired flex modulus to provide for better control and serviceability of associated rails and railway cars.
摘要翻译： 层压木材和封装的铁路连接结构及其相关联的制造方法。 将层压木板条的木芯插入废轮胎橡胶和聚氨酯的挤压套筒中。 聚氨酯粘合剂将木板条层压在一起，并用作润滑剂和粘合剂，用于使套筒围绕芯部放置和固定接合。 端盖牢固地接合在复合套管的每一端，固定在木材或其他天然纤维芯和套筒上。 用于与铁路床接合的纵向槽或槽表征套筒的底部和侧表面。 芯可以设置有孔和凹槽以接收与维持在端盖中的处理器和应答器互连的传感器和导体。 端壳还保持用于铁路连接结构的有源元件的光伏器件和电源。 芯也可以由木材或其它天然纤维制成，使得芯具有所需的挠曲模量，以提供相关导轨和铁路车辆的更好的控制和可使用性。
