Subgrade is an important construction element of the railroad track. In the process of long-
term operation, the subgrade is loaded by trains and exposed to natural climatic factors …

This paper presents the results of a series of large-scale cyclic triaxial tests conducted on
ballast subjected to increased load and frequency of loading. For a given loading, the …

Railway transitions like bridge approaches experience differential vertical movements due to
variations in track stiffness, track damping characteristics, ballast settlement from fouling …

Railway transitions such as bridge approaches experience differential movements related to
differences in track system stiffness, track damping characteristics, foundation type, ballast …

Railroad track transitions such as bridge approaches may experience differential
movements due to variations in track stiffness; impact loads due to train speed and …

The paper describes results of stressed state tests of railway subgrade top in under new-
generation gondola cars with 270 kN axle load. Vertical stresses were measured in 2018 …

The paper describes results of bearing capacity calculations for railway clayey embankment
under new generation gondola cars with 270 kN axle load. Test stretch is situated at the …

Over time railroad tracks have their structural quality varying in function of traffic
accumulation and maintenance. These changes can provoke different track responses in …

Due to an increase in axle loads, the development of excess pore water pressure and
settlement in a railway track foundation of fine-grained subgrade soil can be observed. A …

The measurement of track substructure deflections is an important parameter for the
determination of structural capacity, identification of track problem areas and evaluation of …
