“…Meanwhile, the construction of the highways will change the thermal stability of the permafrost and cause its degradation. Such as the Alaska Highway in the United States, the trans-Siberian Highway in Russia, the Dempster Highway in Canada and the Qinghai-Tibet Highway in China [4][5][6][7]. Therefore, it is a big challenge to build highway in permafrost region, under the dual role of the above.…”

Permafrost covers about 23% ~ 25% of the land in the northern hemisphere, mainly in Russia, Canada, Alaska, Northeast and Qinghai Tibet Plateau (QTP) in China. Many engineering especially the transportation has been in the permafrost regions above. Under the action of highways construction and global warming, permafrost under infrastructures is degraded and causes serious damage. Two phases closed thermosyphon (TPCT) is a widely accepted green countermeasure against the problem in permafrost regions. Although it has been applied to prevent permafrost degradation, their application presents significant challenges on account of the stronger endothermic action of asphalt pavement. This paper focused on the thermosyphon technology and application in the permafrost. Moreover, the article highlighted the excellent working performance of the TPCT that improving the stability of the infrastructures and prevent it degrading due its excellent efficiency of heat transfer. The industrial applications of the TPCT were also summarized, along with their limitations. Finally, the results reported in this paper can provide a valuable guidance for the design of the TPCT and construction of the permafrost regions in the future.

“…In recent years, as a result of global warming, the average temperature in the permafrost regions has risen at about twice the rate of the rest of the world [2,3]. Meanwhile, the construction of highways will change the thermal stability of the permafrost and cause its degradation, such as the Alaska Highway in the United States, the trans-Siberian Highway in Russia, the Dempster Highway in Canada, and the Qinghai-Tibet Highway in China [4][5][6][7].

Permafrost spans approximately 23–25% of the land in the northern hemisphere, primarily found in Russia, Canada, USA, and China. Numerous engineering projects, particularly those related to transportation, are situated within these permafrost regions. Due to the impact of highway construction and global warming, the permafrost beneath the infrastructure is deteriorating, leading to significant damage. Two phases closed thermosyphon (TPCT) is a widely accepted green countermeasure against the problem in permafrost regions. Although it has been applied to prevent permafrost degradation, their application presents significant challenges on account of the stronger endothermic action of asphalt pavement. This paper focused on a review of the thermosyphon technology and application in the permafrost. Moreover, the article highlighted the excellent working performance of the TPCT that improves the stability of the infrastructures and prevents it degrading due its excellent efficiency in terms of heat transfer. The industrial applications of the TPCT were also summarized, along with their limitations. Ultimately, the findings presented in this paper can offer crucial insights for future TPCT design and development in permafrost areas.

“…Reports of damaged infrastructure are numerous in circumpolar regions. Permafrost degradation has adversely affected infrastructure such as the Alaska, Taylor, Inuvik‐Tuktoyaktuk, and Dempster Highways in Alaska and Northern Canada 20,26,27 ; and the Baikal‐Amur and Trans‐Siberian Railways in Russia 28 . Similarly, many engineering challenges caused by permafrost thaw have occurred on the Qinghai‐Tibet Plateau (QTP) Highway and Railway 14,15,22,29 …”

Surface energy balance (SEB) strongly influences the thermal state of permafrost, cryohydrological processes, and infrastructure stability. Road construction and snow accumulation affect the energy balance of underlying permafrost. Herein, we use an experimental road section of the Alaska Highway to develop a SEB model to quantify the surface energy components and ground surface temperature (GST) for different land cover types with varying snow regimes and properties. Simulated and measured ground temperatures are in good agreement, and our results show that the quantity of heat entering the embankment center and slope is mainly controlled by net radiation, and less by the sensible heat flux. In spring, lateral heat flux from the embankment center leads to earlier disappearance of snowpack on the embankment slope. In winter, the insulation created by the snow cover on the embankment slope reduces heat loss by a factor of three compared with the embankment center where the snow is plowed. The surface temperature offsets are 5.0°C and 7.8°C for the embankment center and slope, respectively. Furthermore, the heat flux released on the embankment slope exponentially decreases with increasing snow depth, and linearly decreases with earlier snow cover in fall and shorter snow‐covered period in spring.
