In the North, it seems the interstates and highways tend to get cracks across the entire road at relatively even intervals. I suspect they form where they lay down the rebar supports/holders. It makes sense to me that cracks/"potholes" would form there as it seems that at that point compression of some sort would occur from the weight of vehicles causing the asphalt/road to crumble. While more work to initially build and lay... What would happen if they laid the supports and rebar down like elongated tile or vinyl siding on a house... Never having adjacent pieces ending near each other?
