THE CONCEPT OF THE CLASS OF GEORGICAL STRENGTH OF AUTOMOBILE ROADS AND ITS USE WHEN DEVELOPING AN ALBUM OF TYPICAL STRUCTURES OF SENSITIVE ROAD CLOTHES
On the basis of MADI, a project of an album of typical structures of flexible pavements for federal highways was first developed. The work was performed in the framework of research and development on the request of the Russian Road Agency (Rosavtodor). The design was carried out taking into account modern efficient road-building materials based on advanced domestic and foreign experience. Typical pavements will allow to avoid errors in the design and ensure their effective operation within the standard service life. Typical pavement structures are divided depending on the road-climatic zone, road category, number of lanes, type of soil of the working layer of the roadbed, as well as the class of traffic density of the road. In this article, the concept of the class of cargo density is given, the dimensions of the given daily traffic flow intensity are given in conjunction with the class of density of the roads. An example of typical constructions of flexible pavements of federal highways is given.
