This paper presents an analysis of domestic and international experience in the construction of modern non-rigid pavements. An assessment of existing structures on roads with high traffic volume; designated directory structure of non-rigid pavements, developed on the basis of the research.
Keywords: construction, non-rigid pavement, structural layers, the total number of rated load applications, traffic load class
The article provides analysis of modern methods of struggle with the rut in road clothes with asphalt. Increasing the resistance of asphalt concrete pavements to rutting can be done in two ways: by calculation and improve the composition of the asphalt concrete. Development of methodology for calculation of road constructions on the resistance to rutting will allow us to take the design of pavements resistant to rutting and develop strategies for maintenance activities. Material science solutions to optimize the properties of the asphalt are to improve the properties of binders, use of modifiers, the use of asphalt concrete that is resistant to rutting, such as stone mastic asphalt and polymer-dispersed-reinforced asphalt concrete.
Keywords: road construction, rutting, asphalt pavement, polymer-bitumen binder, the composition of the asphalt concrete, stone mastic asphalt, polymer-dispersed-reinforced asphalt concrete, methods of forecasting rutting
