A state-of-the-art review was delivered in the manuscript to analyze the current situations
and the advantages/disadvantages of resilient deformation related issues to the unbound …

Nowadays, railway system plays a significant role in transportation, conveying cargo,
passengers, minerals, grains, and so forth. Railway ballasted track is a conventional railway …

This paper explains the importance of using a nonlinear anisotropic three-dimensional (3D)
finite-element (FE) pavement model to simulate the granular base layer and predict …

Pavement foundation geomaterials, ie, fine-grained subgrade soils and unbound
aggregates used in untreated base/subbase layers, exhibit nonlinear behavior under …

A new cross-anisotropic model is proposed to predict the performance of granular bases in
flexible pavements. A cross-anisotropic representation has different material properties (ie …

This study aimed to develop a finite element model to simulate the geogrid-reinforced
flexible pavement structure by taking into account the lateral confinement effect of geogrid …

With the current move towards adopting mechanistic-empirical concepts in the design of
pavement structures, state-of-the-art mechanistic analysis methodologies are needed to …

Ballast is an essential layer of the railroad track structure, and provides primarily drainage
and load distribution. In general, ballast aggregates are considered as uniformly graded …

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

Material anisotropy and thin interlayer are very common in layered pavement structures.
Despite many numerical approaches in pavement analysis, very few theoretical methods are …
