Ongoing activities
- Road and railway construction materials (V. Vorobjovas)
Description of ongoing activities
Students are provided with conditions to carry out experimental research of road and railway construction materials in the training laboratory of road and railway construction materials. Here, students combine theoretical knowledge and knowledge gained from laboratory research. In this way, a practical understanding of both the properties of the materials and the values of the properties obtained by research is gained. The laboratory is equipped with equipment and tools that allow students to determine the main properties of materials and learn to recognize the type of material and select appropriate methods to assess the properties. Students learn to recognize the type of soil according to physical and mechanical properties and to evaluate the suitability of the soil for the installation of the bedrock and the peculiarities of cold sensitivity. They determine the water permeability of soils and its dependence on the particle size distribution. Also, determine the dependence of soil density on its moisture. In addition, they are acquainted with the physical properties of aggregates and their classification. Students determine the basic physical and mechanical properties of asphalt mix, asphalt cores, such as apparent, and mix densities, voids content, stability and flow-ability. The equipment available in the laboratory provides a significant experience and stimulates students’ interest in science.
Students learn and solve practical tasks in the fields of planning, design and modelling of cities, its transport and engineering infrastructure in the laboratory.

Description of ongoing activities
Students are provided with opportunities to study and solve practical tasks in the fields of planning, design and modelling of cities, its communication and engineering infrastructure in the laboratory of urban transport traffic. Geographic information systems (GIS), traffic flow modelling and other practical tasks are used to develop skills. Students prepare laboratory work on computers using specialized software - ArcGIS and PTV software package.
During exercises and laboratory work, students are introduced to the principles of traffic flow modelling. Typical elements of the communication system are modelled, experiments related to hypotheses on the improvement of communication systems and comparison of practical solutions are performed.
Regarding the relevant study modules, students are also introduced to geographic information systems (GIS), the different features of ArcGIS software and its capabilities. For the implementation of laboratory works, students use data from geo-information databases (GDRLT) and digital raster orto-photographic maps (ORTLT) of the territory of the Republic of Lithuania.
They are also introduced to the presentation of maps, the creation of databases and the different tools used for spatial analysis. Based on the collected attributes, the analysis of the selected area is performed and 3D models of the areas are created in the ArcScene environment
