Stamp test of railway ballast, stabilized by geogrids

Abstract

In accordance with the objectives of the study, the program of works provided for stamp tests of ballast reinforced with geomaterials. The need for stamp tests is primarily due to the lack of reliable data to assess the impact of geomaterials on the stabilized railway ballast deformability. Thus, the main purpose of the stamp tests was to study and evaluate the impact of different geomaterials types on the crushed stone deformation properties in different reinforcement variants in a wide range of operating loads.
