Ah, right. Obviously. Because the same amount of water needs to change phase.
Still, in that time this road will be walkable, while others may not. And you still avoid the piles of snow and salt runoff that come with a non-heated surface.
Depends on sunlight, and the color of the pavement. For dark asphalt, simply preventing a dusting of white snow goes a long way at converting the sunlight into heat, basically for free.
It takes much less energy to prevent the accumulation in the first place. Which is the goal with this sort of setup.
It takes exactly the same amount of power. It’s just spread over a longer time period.
