What is it about?
This paper presents numerical simulation using the Discrete Element Method (DEM) to to study the interface behaviour of coal-fouled ballast reinforced by geogrids subjected to direct shear testing.

Why is it important?
The advantages of the proposed DEM model in terms of capturing the correct stress-displacement and volumetric behaviour of ballast, as well as the contact forces and strains developed in the geogrids are discussed.

Perspectives
The Proposed DEM model can be used to predict the shear stress-strain behaviour of railway ballast considering the inclusion of geosynthetics under a given level of fouling.
