Frost Heaving in Ballast Railway Tracks
Procedia Engineering, 2017 Abstract Frost heave is a well-known phenomenon in cold regions. It may happen in the wet clayey ground during winter in seasonally frozen regions and during autumn to winter in active layers in permafrost regions. The railway track upheaval, which happens in cold regions, is generally understood as due to frost heaving in subgrade layers.

Advances in Materials Science and Engineering, 2022 Due to the complex dynamic interactions of the vehicle-track system in the turnout of high-speed railway stations on a ballasted track, the geometric position of the line changes rapidly. In order to improve the stability of the line, the ballasted track

Behaviour of under-track crossings on ballasted railways [PDF]
Transportation Geotechnics, 2019 Abstract Signal and telecommunications (S&T) cables and other services often cross underneath a railway line in a duct or conduit, buried in the ground below the ballast. These under track crossings (UTX) are likely to increase or decrease the track support stiffness compared with the surrounding ground, depending on the material and construction ...

Experimental Study on Settlement Behavior of Ballasted Tracks with Polymer Compound-Coated Gravel
Applied Sciences, 2022 The ballast used in ballasted railway tracks transmits load from the rails and ties to the subgrade during train travel, and directly affects the overall track support performance and elastic behavior of the ballasted track.

A dynamic model of ballasted rail track with bituminous sub-ballast layer [PDF]
, 2012 The bituminous sub-ballast layer within the ballasted rail track allows some mechanical and environmental advantages. An analytical model of a ballasted rail track with sub-ballast layer has been proposed by considering the rail as viscous-elastic ...
