Same with any roadway. The base is everything. I visited some European contries and noticed that the roads seemed to have fewer cracks and potholes than many roads in the US.

- volkl48 10mo agoMost of Europe sees far fewer freeze-thaw cycles than most of the US does, which are a huge killer of roads. The color scales aren't equivalent here but you can see the difference: Europe - pretty much only unpopulated northern Scandinavia + up in the Alps/Pyrenees getting over 64 days, most of the most densely populated areas with lots of infrastructure below 32 days: https://www.atlas.impact2c.eu/en/climate/freeze-thaw-days/?parent_id=22 https://www.atlas.impact2c.eu/en/climate/freeze-thaw-days/?p...
