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?

Answer 1

This does happen over time, but every half game there is a re-pebble done. Part of the strategy is figuring out what is happening as the ice speeds up/changes over the course of the match.
