Residents of the Moscow region, who will answer the question: what hell is the railroad on the MKAD in the extreme left and not in the extreme right?

Alexandra answered... Oh, I’m chatting.
I answered t.k. At the time, he was engaged in research, including in the MCA. In short, asphalt is sensitive to any dynamic loads, weight is just one of them. If you pay attention - often the tracks become noticeably closer to the lighting - because there are more frequent sharp brakes. The left rows of the MKAD are somehow attractive for riders, and the tracks there appear faster. 10 years ago (now I don't know, I've been doing other things for a long time) they tested new "stable" types of asphalt concrete (parts of 1-2 km).
But that’s why there’s no track in the far right – the question is more interesting. Here you want to ask the author of the original quote about the number of measurements carried out (well there, for example, 10km through every 50m for each row) and whether he conducted a study of documentation on previous repairs, or maybe in the right row the dull asphalt is fresh?
