Study of Ballast Fouling in Railway Track Formations
Indian Geotechnical Journal, 2012This article presents an overview (requirements) of rail track aggregates, the ballast gradation adopted in railways in different countries and their comparison with Indian ballast gradation, drainage of rail track and ballast fouling in India. Further in situ ballast sampling, testing and ballast fouling quantification are also presented for typical ...

Model Testing of Two-Layer Railway Track Ballast
Journal of Geotechnical and Geoenvironmental Engineering, 2000Railway track ballast requires regular attention to maintain line and level. A recently developed maintenance method, known as pneumatic ballast injection (PBI) or stoneblowing, re-levels and realigns the track by lifting the sleepers and track and blowing smaller size gravel between the ballast and the base of the sleeper.

Railway track formations generally consist essentially of a layer of coarse aggregate, or ballast, in which the sleepers are embedded (see Fig. 12.1). The ballast may rest directly on the subgrade or, depending on the bearing capacity, on a layer of blanketing sand. The layer of ballast is intended to provide a free draining base which is stable enough

Beam-track interaction of high-speed railway bridge with ballast track
Journal of Central South University, 2012Based on the construction bridge of Xiamen-Shenzhen high-speed railway (9–32 m simply-supported beam + 6×32 m continuous beam), the pier-beam-track finite element model, where the continuous beam of the ballast track and simply-supported beam are combined with each other, was established.

Vertical load distribution in ballasted railway tracks with steel slag and limestone ballasts
International Journal of Pavement Engineering, 2017Over the last few years, use of steel slag ballast as an appropriate material instead of conventional stone ballast has gotten more attention by railway owners in various countries.

Three-dimensional modelling of high speed ballasted railway tracks
Proceedings of the Institution of Civil Engineers - Transport, 2013In the present paper, a three-dimensional dynamic railway finite-element model, is utilised to study the geotechnical performance of high speed railway tracks. This model takes into account many of the railway track components such as multi-layered ballast and subgrade, nonlinearity in resilient behaviour of the sub-soil, and track–train interaction ...

Performance of geosynthetic reinforcement on the ballasted railway track
Lowland Technology International, 2015Geosynthetics provide an important option to improve track support stabilization and thereby reduce the track maintenance costs and operation costs due to train delays. In railroad construction, geosynthetics may be installed within or beneath the ballast or subballast layers.

Qualitative analysis for dynamic behavior of railway ballasted track
2014Schottergleise sind infolge ihrer dynamischen Belastungen und weil sie aus verschiedenen Materialien und Komponenten bestehen, nicht leicht zu prüfen und in ihrem Verhalten vorherzusagen. Für die Beurteilung der Schotteroberbauqualität sind daher Gleisdesign, Instandsetzung und effektive Wartung wichtig.
