Complex Solutions for Providing Roadbed Stability on Permafrost

The paper gives examples of determining the causes of roadbed deformations and its strengthening on the Baikal-Amur Mainline and Amur-Yakutsk Mainline, the Berkakit-Tommot section. The main principles determining the construction in permafrost areas are, on the one hand, low capital and running costs of an immediate normalization of engineering and geological processes (those of the frozen ground first of all) in the bases of natural and man-made systems (earth structures-roads), and on the other hand, an adherence to a balanced thermoregulation of developed areas within their landscapes. The goals of all conservation and anti-deformation measures that provide a stability of natural and man-made systems are achieving high strength characteristics of the roadbed soils and its subgrade in shortest time and providing the longest period of their service.
