“…In the future, we would like to continue the complex analysis of the impact of modal split with consideration of changing climatic conditions, pavement maintenance, and serviceability factors [64,65]. The presented research activities will be extended by analyses of other significant effects of the modal split in favor of PuT.…”

Traffic volume depends on several indicators. The most important are the degree of motorization, mobility, and especially the travel time and travel cost factor. The article presents an analysis of the possibility of using mobility surveys and traffic counts to achieve a balance between supply and demand. The frequency of congested traffic and over-capacity volumes are determined. By analyzing the trip information captured in the mobility surveys, we detected the strata causing the highest demand—economically active people with “job” as the purpose of their trip. The study area includes the Kysuce region and the city of Žilina in Slovakia. Three scenarios are processed in the article. Scenario 0 defines the current state, scenario 1 defines the situation with free-of-charge public transport, and scenario 2 represents a targeted modal split where saturation is not exceeded. The aim is to shift passengers to public transport and increase the share of public transport in the modal split. Scenario 2 is also presented in terms of saved emissions as an additional factor of relocating passengers from private to public transport. In terms of fare, we found a small change in the modal split with free-of-charge public transport.

“…The road pavements should be designed, built, managed, maintained, recycled at a reasonable price, in reasonable quality, respecting the relevant requirements of users, residents and sustainable development throughout the life cycle. Pavements, as important landscape ecological elements, should be designed regarding current climatic change [20,21], with respect to aesthetic principles considering the cultural and natural wealth of Slovakia. Of the wide range of required credibility inputs of pavement management system [3,23], specific attention is paid to the degradation model and rut depth development functions from the number of passes of all vehicles, Fig.…”

Authors have long been guided by the following premise in their research, educational, professional and publishing activities. Components of the Integrated Transport Infrastructure (ITI) of Slovakia, including roads, should be designed, built, managed, maintained, recycled (decomposed) at a reasonable price, in reasonable quality, respecting the relevant requirements of users, residents and sustainable development throughout life cycle. Elements of ITI Slovakia, as important landscape ecological elements, should be designed with respect to aesthetic principles considering the cultural and natural wealth of Slovakia. Slovak technical universities have recently been criticized for teaching 50-years-old curriculum. The authors dare to disagree with the statement and, due to their scientific profile, pre-sent their partial outputs of a holistic approach to the sustainability of transport structures with a priority focus on pavement. In the intentions of the above mentioned, it could perhaps be partly convergently concluded that they learn new things in the field of transport construction, but under the old names.

“…Since 2003, the research of the transport departments of the Faculty of Civil Engineering has been concerned with the verification of the influence of non-transport loads on the freezing of the railway track structure [1][2][3] and pavement construction [4,5]. Since 2020, the research activities have also focused on the verification of the influence of traffic load (its static and dynamic components) on the sub-ballast layers depending on the deformation resistance of its individual structural layers.…”

Glass waste decomposition time in landfills or the countryside can exceed several millennia. Recycling and finding new uses for municipal waste, where glass accounts for approx. 10 % of the volume, is therefore essential to ensure the sustainable development of society. A novel method of reusing glass waste is to produce a thermal insulation material called foam glass in the form of boards. The manufacturer characterises the foam glass boards as having extreme compressive strength and being suitable for highly loaded building structures. The Department of Railway Engineering and Track Management (DRETM) has been long-term researching the possibility of applying various thermal insulation materials (composite foam concrete, Liapor concrete, extruded polystyrene boards) to the sub-ballast layers. For the above reasons, an experimental field was constructed to validation a modified design of the sub-ballast layers with embedded foam glass boards. The paper’s objective was to verify whether the modified composition of the sub-ballast layers affects the increase of its deformation resistance. The assessment of the deformation resistance of the sub-ballast layers of the modified and standard construction was performed by a series of static load tests in the particular structural layers.
