Impact of the sand bed on stability of cobblestone pavement

The observation of public transportation bus bays in Lublin (and probably in other cities) made of concrete or stone blocks pavement shows that on many streets it is not very durable. The assessment of its durability was made for traffic on the KR-3 and KR-4 using mechanistic method that is used for road surfacing on the basis of its own program of multilayer systems in cylindrical coordinates. The article presents the results of the studies of typical constructions at public transportation bus bay.
