They can put electricity under the runway for the taxi and navigation lights. Why can't they make or use a heater system? Under the runway? The wetness is ok from the de-icer, and melted ice. The guy said the moisture came up when the plane landed, so that's not ideal, but it's acceptable.
Good idea, but I'm wondering if they can't put an electric or hydronic snow melt system either due to the high cost or because the runways take a lot of punishment from the very heavy aircraft that land there...but I agree with you it's a bit of a no-brainer. Ofc you'll put many people out of work that handle snow, unless it's just for the runway portion.
Heated asphalt ? If a top league football club can afford to heat a grass pitch it i’m sure a major international cargo hub can afford to heat at least one runway.
