Lateral resistance of railway track is one of the most important parameters in lateral stability. This parameter depends!on the conditions of different components of ballasted railway track (such as density of ballast layer, sleeper spacing, type of sleeper, etc.). From this perspective, type of sleeper has an important effect on lateral resistance. However in some conditions, in technical and ...

A ballasted railway track system comprises several components among which steel rails, rail fasteners, timber, steel or concrete sleepers, granular ballast, sub-ballast, and subgrade materials are the main parts. Railway track systems are constructed to provide a smooth and safe running surface for passenger or freight trains. They are designed to sustain the force of lateral, longitudinal and ...

Alternative sleeper technologies have been developed to address the significant need for replacement of deteriorating timber railway sleepers. The review literature indicates that sleepers might fail while in service, despite passing evaluation tests current composite standards which indicated these do not represent situ on ballast. In this research, a new five-point bending test is evaluate fl...

The present contribution deals with the numerical modeling of railway track-supporting systems-using coupled finite-infinite elements-to represent the near and distant field stress distribution, and also employing a thin layer interface element to account for the interfacial behavior between sleepers and ballast. To simulate the relative debonding, slipping and crushing at the contact area betw...

In recent times, the shape of beams evolved from wooden sleepers and then to steel until they reached concrete sleepers. These play a very important role in transferring loads train wheels subgrade layers fixed by railway. This development took place we mono-block paper discusses, through laboratory experiments, effect ultra-high performance mixtures on behavior sleeper B70. The ability these n...

Over 50 years, a large number of research and development projects with respect to the use of cementitious and concrete materials for manufacturing railway sleepers have been significantly progressed in Australia, Europe, and Japan (Wang, 1996; Murray and Cai, 1998; Wakui and Okuda, 1999; Esveld, 2001; Freudenstein and Haban, 2006; Remennikov and Kaewunruen, 2008). Traditional sleeper materials...
