Abstract
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.

Summary
The sustainability of the road network is under ever-increasing economic, environmental and social pressures. Road infrastructure users are demanding higher and higher benefits from road administrators for their private as well as public financial resources This represents, in particular, a combination of ensuring higher road safety level, acceptable time availability of destinations, and economic efficiency in the processes of road infrastructure management by administrators. These, as well as other regulations and restrictions, challenge the whole sector to find new or improve existing solutions that have innovative features. Their goal is to move the whole society forward and at the same time in terms of sustainability rules, they will not generate adverse effects for future generations
