Description
Runways on frozen ground face a thaw threat as the world warms. Xiaolan Liu and co-authors tested a vented road bed design to keep the cold in, in work from twenty twenty-five. Flat, wide runways soak up heat, which softens the frozen base. Their design runs pierced vents side by side under the surface.
A computer model was checked against past lab data on air speed, rock layers, and heat depth curves. With warming and earth heat both in play, the vented bed held ground below ten meters in a frozen state for thirty years. The chill effect fades with depth and over time, then levels off. The rock layer gained most from the vents. The team offers the design as a base for lasting polar builds.
