Construction of Railway Track Using Asphalt – Ballast Layer
Engineering and Technology Journal, 2012 The work presented in this paper focuses on new trends in the construction of rail track using asphalt ballast layer. Model tests were performed with ballast layer 150mm or 200mm. These thicknesses are the common range used in railway construction. Overlaying a sandy layer 400mm in thickness.

Study of ballast layer stiffness in railway tracks
Građevinar, 2016 In this paper, ballast layer stiffness in railway tracks is investigated. Test results show that the percentage of ballast contamination changes considerably across the ballast layer depth. For this reason, the ballast was divided during modelling into three layers and the stiffness of each layer was derived based on the pyramid model developed for ...

MODELING THE RAILWAY TRACK BALLAST BEHAVIOR WITH HYPOPLASTICITY
Journal of Mathematical SciencesAbstract The contact problem describing a railway vehicle — road — track ballast system is under our investigation. During the motion, the rolling stock (snowpiercer) is represented by a moving localized load, the road by a Timoshenko beam, and the track bed material is rigorously modeled using 3-by-3 matrices of stress and strain rate.

Design of Ballasted Railway Track Foundations under Cyclic Loading [PDF]
Slope Stability, Retaining Walls, and Foundations, 2009 The foundations of ballasted railway tracks are usually consisted of a graded layer of granular media of ballast placed above a naturally deposited subgrade. Available methods for design of track foundations are based on determination of an adequate granular layer thickness of ballast so that subgrade shear failures and plastic deformations produced by
