Synthetic sleepers(made of fiber reinforced polyurethane foam) is the best choice for the construction of railway bridges. Compared with conventional natural wood. Moreover, installing Synthetic sleepers on railway bridges has significant additional benefits

As the China's biggest manufacturer of Rail Fasteners for conventional railway in China, Anyang Railway Equipment Co., Ltd(AT) has been providing good quality goods for the Railway Constructions not only in conventional Railways, but also for Metro, Urban Transit as well as High-Speed Railways.

Recent developments in composite materials have resulted in their pilot adoption in railway industry, such as ‘fiber-reinforced foamed urethane, ‘geopolymer concrete’, ‘recycled polymer’, and ‘CarbonLoc composite’. Railway track support systems are critical for the safe and reliable operations of railway tracks. There are two types of support structures, which can be designed to be either a slab or a cluster of discrete bearers or sleepers. The choice of turnout support system depends on asset management strategy of the rail operators or maintainers. The aim of this paper is to present the criteria, fundamental and multi-disciplinary issues for the design and practical selection of composite materials in railway turnout systems.

The types of railway sleepers include: wooden sleepers, reinforced concrete sleepers, plastic sleepers, concrete sleepers, steel fiber concrete sleepers, steel sleepers, synthetic sleepers, each type of sleeper has its advantages and disadvantages.
