Have you idiots ever driven in a cold winter climate? Frost comes out of the ground every spring in varying degrees depending on the preceding winter. It depends on a number of factors, like what material the road/airstrip was made from, and how much time and care they took building it. Did they have good compaction or not? Trust me, I am an old road builder.
What intelligent human builds anything on top of ice, other than a fishing house for weekend escapes. Build on ice? This is not the 1800s.
