Abstract

Preparations for the future construction of high-speed railway lines across the territory of the Czech Republic have begun in the Czech Republic with the aim of connecting it to the European network. This article describes findings from a project focused on the optimization of the substructure of high-speed railway lines with an asphalt layer and the inclusion of a multi-axial geogrid. A number of full-scale laboratory experiments were carried out at the Czech Technical University in Prague. The result of laboratory tests, which included both static and dynamic load modes, is the design of an optimized sub-ballast structure for the use in high-speed railway lines.
