Abstract: The deformation and degradation of fouled ballast have been examined by large-scale triaxial tests and discrete element modeling (DEM) to understand how clay fouling changes the shear strength and micromechanical aspects ...

Abstract: This paper presents laboratory and field test results on the use of tire cell track foundation (TCTF) consisting of an assembly of infilled rubber tires to reinforce capping material below the ballast layer. Large-scale ...

Abstract: Despite the reduced size and angularity failing to meet the conservative ballast standards of some countries, the recycled ballast still retains significant mechanical characteristics for potential reuse. This study ...

Abstract: Rail tracks deteriorate over time due to dynamic wheel loads, a process that necessitates frequent and costly maintenance. This paper presents the results of laboratory and field tests on the application of a recycled ...

Abstract: This paper presents a study of the load-deformation behavior of geocell-stabilized subballast subjected to cyclic loading using a novel track process simulation apparatus. The tests were conducted at frequencies varying ...

Abstract: This paper presents results obtained from the discrete-element method (DEM) to study the effects of particle shape on the shear behavior and breakage of ballast aggregates. In this study, a series of direct shear tests ...

Abstract: This paper presents a novel approach to smoothen the abrupt stiffness variation along railway transitions and provides a step-by-step design of a multistep transition zone comprising adjoining segments with changing stiffness ...
