In this article, the authors explore examples of preserved cultural heritage related to traffic structures, focusing on the world's oldest bridges in Europe and Slovakia, as well as the oldest preserved roadways. They delve into the detailed history of Marians Square in Žilina, particularly its surface treatment, drawing from credible historical sources. The article also presents comparisons of elasticity modules and deformations of the roadway, based on measurements taken in 1966 and the last reconstruction from 1995 to 1997, which cost SK 64.5 million (equivalent to EUR 6.9 million in 2024). Through an evaluation of mechanical characteristics and environmental criteria, the authors conclude that the reconstructed road, even in 2024, effectively protects against frost damage, minimizes particulate matter and noise pollution (excluded motor traffic), and adheres to principles of contextual design for pavements.

The article presents the possibilities of utilizing waste from the automotive industry, namely old tires, in constructing pavements. The application of shredded rubber creates conditions for devulcanization, which improves the rheological properties of the binder and ensures its better dissolution in asphalt. The focus is on assessing the condition of the pavement surface, measuring the noise level in the vicinity of the road, and quantifying and evaluating the cost of implementing an asphalt pavement design with a crumb rubber modifier (CRM). A visual inspection was performed after 6 years of pavement life. Based on the inspection outputs, the pavement surface structure was in a favourable condition with no permanent deformations. Verifying the acoustic properties showed a noise reduction compared to the road section with the modified asphalt pavement surface. Currently, the price of rubber-modified asphalt for pavement in Slovakia is on average 10 to 15 % higher than the price of other modified mixes. However, we can conclude that pavements with CRM are economically and especially ecologically more advantageous in the long run.

The authors present the law protection of cultural monuments in the Slovak Republic and the outputs of an interesting case study, more specifically the creation of a 3D model with real textures of Hricov Castle, which was created in 2019 with additional improvements done in 2022. Ruins of Hricov Castle are located in the village of Hricovske Podhradie, 15 km from Zilina. For model creation, devices obtained within the project of the Broker centre of air transport for the transfers of technology and knowledge into transport and transport infrastructure was used. The 3D model of Hricov Castle created by team leader Tomas Cesnek currently presents one of the most realistic Slovak digital 3D models created by laser scanning technology. This model will be a part of the permanent exhibition of Hricov Castle in the historical toll building from 1556 in Dolny Hricov, Slovakia, the reconstruction of which is ensured by the members The Association of Friends of Hricov Castle. Model creation methodology and the use of special textures should be used to produce more realistic laser scan 3D models.

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.
