izardIt is common knowledge that road quality in Russia is either poor, or fair but in later case roads should be repaired often. The root cause of this eternal curse is Russian climate that is deadly for road surface. Water freeze/melt cycle happens almost daily in autumn and spring, and even few times during winter.
I lived here in Munich through 2 winters and observed that local mild climate means that water freeze/melt cycle happens more frequently than in Russia - almost daily. Roads are still good however.
Here is why:
This is a road next to our place. It is not road works - they replace some water tubes (of course, this does not mean there is an interruption in cold or hot water supply).
One can see that the road consists of 20cm layer of asphalt, laid on 50cm layer of concrete, then goes more then 1m thick layer of gravel. Apparently, it means that there is no need to repair it often.
