The research works conducted in the Department covers theoretical and applied mechanics, the design of the road, airport, and rail pavements, as well as the issues of soil mechanics and the interaction of the subgrade with the structure. The research interests of the employees of the Department include also modeling of the constitutive properties of engineering materials, methods of numerical analysis of structures, and research in the field of vibration and noise reduction caused by means of communication (mainly railroads, subways, and trams).
Main fields of research activity:

• Dynamics and rheology of road, airport, and rail pavements, taking into account elastic-visco-plastic properties of materials;
• Modeling the constitutive properties of engineering materials (soils, asphalt mixtures, shape memory alloys);
• Load capacity and durability of traffic pavement structures (application of mechanistic methods);
• Vibrations of elements of engineering structures caused by moving loads;
• Stability and dynamics of structures on subsoil;
• Structure stability and vibrations under the influence of impulse and shock loads;
• Calculation methods (analytical and numerical, including FEM) in the analysis of traffic pavements;
• Hydraulics of bridges and culverts;
• Drainage of transportation infrastructure.
