Under the influence of climate change, the permafrost degeneration on the northern hemisphere has been accelerated, causing deformation on engineering constrictions as paved roads from thaw settlement, especially in ice-rich permafrost regions. Thus, the paved road construction in permafrost regions, under such adaptation technology and designs to climate changes, is one of the most important tasks and presents an ultimate test for permafrost engineers and scientists. In the permafrost regions, there are many engineered solutions available to stabilize paved road embankment materials. These solutions have been classified using a descending order of perceived thermal effects from active cooling to passive cooling such as thermosyphons, cooling pipes, block stone embankments, shading boards, and insulation embankments. Along paved roads in warm permafrost zones, significant settlement and deformations related to creep were found at many places where the embankments are unusually tin in Mongolia. Therefore, the stabilization of the embankments must be taken into consideration based on active cooling and passive cooling methods, we tested out the thermosyphon in natural condition, Mongolia. We are actively building the auto road connecting the aimag centers, the western vertical road. This road network crosses the permafrost in some parts. Serious deformation and settlements took place on road surface in permafrost regions. We have investigated along the roads in Buraat pass in Bayan- Ulgii province, using the drilling, electric resistivity tomography, relative settlements, and temperature measurements. The amount of relative settlement was approximately 20- 40 cm on road surface within 3 years after construction and 5-10 cm within 1-2 years after construction and the permafrost thaw was observed from top of permafrost.
