Functioning of temporary logging roads in winter and off-season periods (a case of the Republic of Karelia)

This article focuses on the analysis of patterns of functioning of forest roads on the example of the Republic of Karelia. At present, most of the logging volumes are in the winter period. However, according to the literature, it is known that climate change may be one of the reasons for the accelerated development of transport infrastructure throughout the year. Taking into account economic feasibility and technical feasibility, in the near future, the problems of improving forest roads of all kinds remain topical. The object of research in the article are temporary forest roads. The subject of the research is the patterns of functioning of temporary forest roads in the winter and off-season periods. The goal of the work is to substantiate recommendations for improving temporary forest roads during off-season periods. Used methods of mathematical modeling and the results of experimental studies. The features of temperature deformations of the unpaved roadbed, which may cause the destruction of the roadway, are considered. The main result is the justification of restrictions on the movement of vehicles on forest roads, if the temperature is minus 3 ° C and above.
