Abstract
The surface of the tunnel lining issues various problems such as cracks due to the cold weather. It is necessary to reduce the recovery costs by means of developing new recovery techniques. However, the research on reducing the damage of road tunnel lining caused by cold weather has not actively been conducted. Hence, this paper analyzes the effectiveness of using insulating materials such as aerogel and heat insulating liquid in enhancing insulating capability. The results show that these materials are effective in reducing heat transfer, confirming damage reduction in cold weather.
