A Review on Composite Railways Sleepers; Recent Developments, Limitations & Future Perspectives

Abstract

Anurag Singh and Atul Kumar Seth

The current review on a number of composite railway sleeper technologies have been developed, there are still few places where they are used in rail tracks. This report thoroughly examines recent advancements in composite sleepers and discusses the major obstacles to their broad adoption and use. Currently, there are a variety of composite sleeper technologies on the market, ranging from those made of recycled plastic that have few or no fibers to those that have a lot of fibers. Although recycled plastic sleepers are inexpensive, employing them poses significant difficulties because to their poor stiffness, strength, and dynamic qualities, which are frequently incompatible with those of timber. The exorbitant cost of high-fibre sleepers, on the other hand, prevents their widespread use. Further limiting their use is the lack of information on the historical long-term performance of these new and alternative materials. This research also presents potential design strategies for resolving the obstacles to the use and adoption of composite sleeper technologies.
