The aim of this project is experimental monitoring, mathematical simulation and verification of railway subgrade structures applied in the Slovak railway tracks.

It is expected to realise experimental measurements and mathematical simulation at various border conditions from the point of view of soil formation design and of the applied conventional but also new materials to the railway subgrade.

These materials are differentiated by chosen physical – mechanical properties so it would be possible to take various thermo-technical properties and final thermal resistance into account.

The result of the project should be a methodology of design and assessment of railway subgrade from the point of view of unfavourable impact of frost also in relation to the changed climatic conditions, as a base for the prepared revision of the regulation S4 Railway substructure.

The optimisation of the technological procedures for the construction of subgrade structure for modernized, upgraded and rehabilitated railway sections by applying various methods and technology sets, taking into account the requirements of economic proposals for its implementation and maintenance.
