Land is one of the most important natural resources; its use is determined by several factors, especially resources and infrastructure. Without proper land management and maintenance as well as after abandoning the land favourable conditions arise for land degradation. Land degradation processes are also found in road infrastructure, which are promoted by various risk factors. In order to ensure the sustainable development of land use, it is necessary to evaluate the causes of land degradation risk, identify the degraded areas and areas that are exposed to degradation risk, as well as identify the possibilities for their elimination. The main risk factors for land degradation in the management of state road infrastructure are: errors in determination of roads and abutting property borders as a result of land reform; land reservation for state road infrastructure development objects; non-cultivated land after completion of construction works; activity of beavers and expansion of invasive plants. The aim of the article is to evaluate the main types of land degradation in the management of state road infrastructure and to determine the risk factors. In the article the manifestations of land degradation and the risk factors in the management of state road infrastructure have been explored and summarized. The risk factors of land degradation have been classified according to the type of degradation.
