Back during World War II, the Japanese could crater a runway one day and the Seabees would have it operating the next. I forget what they called those preformed runway slabs but sometimes there was a stack of those around which could be dragged into place mere hours later.

I’m pretty sure they were actually sheets of grated steel.
