In Eastern Europe, especially before the iron curtain was scrapped, the runways, were made of good old concrete blocks. These blocks were very often poorly matched together making the surface quiet rough.
This reminds me of Cairo, some years ago, when the Russians had greater influance there.
5R/23L was especially rough with this type of construction, altho winter ice was (fortunately) not a problem.
Now, all nicely paved over, this is now long forgotten, but at the time, provided a very rough ride.
