The development of new materials and structures, physical and mathematical methods and information technologies refer to some of the most pressing problems of increasing the reliability and durability of road structures in the North. The causes of road failures in severe natural and climatic and difficult ground-geological conditions are not so much the impact of vehicles, but the impact of natural factors on the road. This article presents materials of engineering and information support for theoretical, laboratory and field studies of the structures of the roadbed in permafrost and wetlands, erected from local “substandard” soils. The reliability of using soil massifs is ensured by the wide application of geotechnical materials and modern road-building machines and complexes, the development of computational and experimental studies.
The authors show that for effective work to improve reliability and durability in the North, it is necessary to have and use information technology that includes databases on the natural and climatic conditions of the objects being created, on the parameters and methods of physical-mathematical modeling of processes occurring in the earthwork, regulatory and reference data, on the results of analysis of monitoring studies of similar facilities. In addition, a subsystem of information support for experimental research of road structures in the laboratory and in full-scale conditions has been created. The developed technology includes the use of the created information system at all stages of research and development, which is replenished with the results obtained. The results of the work are summarized in the technical standard.
