Abstract
The results of scientific researches and engineering calculations of rational structures parameters of highways are presented in the paper. All the calculations and researches done were carried out relatively to a highway section in the Russian Far East. This road is being built in severe climatic and complex engineering and geological conditions. This is the area of permafrost occurrences and widely spread deep season freezing. The usage of a geomaterials in the structure allows to lessen considerably the volume of expensive hard mineral volcanic filling of high quality. Numeric modeling of the structure behavior was done using a programming geotechnical complex, an “FEM model”. This allowed to give a quantitative and qualitative assessment of freezing and thawing processes in conditions of annual cycle construction. Effective measures to provide operational reliability for the rational engineering solutions for highways in Northern territories of the Russian Far East were worked out on the basis of the achieved results.
