The Žilina airport was after almost 50 years of use measured by non-invasive methods including GPR and Profilograph GE in order to investigate the quality of the runway pavement at the chosen spots. Since it was just a pilot action, a sample of survey was carried out. The testing spots were placed where the geologic drill core J02 have been drilled out. The measurements performed by Profilograph GE were used to verify the quality of the pavement surface in term longitudinal unevenness by means of index IRI and C. The GPR survey was performed in 3D geometry, hence in the x- and y-direction. A horn type antenna with central frequency of 2 GHz was used on the test field in order to verify the thicknesses of pavement construction layers. Here, the result of a 3D survey is presented. The investigation confirms two sub-horizontal construction layers of the runway pavement. In some areas the GPR interpretation was not possible due to the signal attenuation. This significant signal attenuation is found mainly in the areas where the linear cracks are situated.

Ensuring the sustainability of road infrastructure cannot be achieved without the continuous application of new knowledge and approaches within individual management steps. A particularly risky stage in the life cycle of existing roads is the operation phase. High attention is paid to the environmental, financial and social impacts and benefits of individual processes applied by road managers. These processes meet in pavement management systems (PMS), which, however, cannot work reliably without the necessary input data. Information on the development of the technical condition of the road can also be included among the most important data. The paper brings the first outputs from several years of research of measurements on the Slovak 1st class road. Its aim is to gradually determine the degradation functions for the needs of Slovak geographical, climatic and transport conditions. The secondary objective is to verify the reliability of non-destructive measurement procedures of the technical condition of the road. Emphasis is placed on the application of such mathematical procedures that can not only reliably bring about the determination of past developments in the roadway, but can also present the expected picture of future developments.

Currently, we are experiencing an ever-increasing demand for high-quality transportation in the distinctive natural environment of forest roads, which can be characterized by significant weather changes. The need for more effective management of the forest roads environment, a more direct, rapid response to fire interventions and, finally, the endeavor to expand recreational use of the woods in the growth of tourism are among the key factors. A thorough collection of diagnostic activities conducted on a regular basis, as well as a dataset of long-term monitored attributes of chosen sections, are the foundations of successful road infrastructure management. Our main contribution to this problem is the design of a probe for measuring the temperature profile for utilization in stand-alone systems or as a part of an IoT solution. We have addressed the design of the mechanical and electrical parts with emphasis on the accuracy of the sensor layout in the probe. Based on this design, we developed a simulation model, and compared the simulation results with the experimental results. An experimental installation was carried out which, based on measurements to date, confirmed the proposed probe meets the requirements of practice and will be deployed in a forest road environment.
