In Curling, how come the ice doesn’t melt over repeated ends, then create ruts and paths for the rocks altering how they glide?

Question

Watching the Curlers at the Olympics I see them spend so many trips up and down the ice and so many throws. But the surface stays pebbly and nice, not melting with pools of water and channels that get ground down from the rocks being repeatedly thrown over the same area. How come there is no degradation? Is the surface a compound? Is there a chemical involved that moderates the ice?

Short answer, there is a lot of discussion as to how curling works and there is no consensus on the science. Here is a video that should help from “Smarter Every Day.”
