Ballasted Track versus Ballastless Track
Key Engineering Materials, 2015First concrete sleepers were made of normal reinforced concrete and used during the 1930s and 1940s. Concrete railroad ties became popular in Europe after World War II because of the advances in design, material quality and production of pre-stressed concrete. Now as before, concrete sleepers on ballast represent the primary basis of track construction,

Advanced Rail Geotechnology - Ballasted Track
2011Ballast plays a vital role in transmitting and distributing train wheel loads to the underlying sub-ballast and subgrade. Bearing capacity of track, train speed, riding quality and passenger comfort all depend on the stability of ballast through mechanical interlocking of particles.

Ballasted Track Superstructures: Performance of Innovative Railway Sleepers
Civil-Comp Proceedings, 2012A railway sleeper is the structural element which transversally connects the two rails by means of fastening components, thus ensuring its gauge. Its additional function is to firmly secure the track to the ballast and to distribute the loads transferred from railway carriages to the ballast. One of the most important parameters in the characterization

Ballasted Track Maintenance Modelling Using DEM
2021The ballast layer is a crucial component of railway tracks and it is hence essential to maintain it using adequate processes like tamping and stabilization. These will ensure that the density of the ballast layer is high enough to avoid shearing and settlement of the track under traffic.

Modulus of elasticity of non-ballasted track
BRIСS Transport, 2023The main stiffness properties that determine the stresses in the track structure components under loads from a moving train are the modulus of elasticity of the rail slab and the slab-track/rail correlation stiffness coefficient. These parameters have been investigated for a ballasted track and are well established today, in contrast to those of a non ...

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

Micromechanics Modelling of Ballasted Tracks
1995The purpose of this paper is to study the stability of the ballast submitted to a cyclic loading. Naturally, the behaviour of the ballast is linked with the granular nature of the ballast. We propose here a mechanical model at the grain scale.
