Question:
When new highways are constructed in the northern regions of the US, there appears to be some kind of heating element embedded in the concrete. Is this so, and if so how do they work and how are they activated when it snows and or you have freezing conditions?


Replies:
Heating elements would indeed be very expensive. It is Rebar (reinforced bars for concrete), that gives the roadway greater load carrying capacity. It is not only used in the northern US.
