Abstract
The existing practice of design calculation of road pavements demands improvement in methods of temperature change forecasting in each layer considering the actual thermophysical characteristics of materials, and improvement of definition methods of the intense deformed condition of layers build with thermoreologicaly sensitive materials. For more exact analysis of thermomechanical processes in a pavement structure, in this work it is done computer modeling of thermoreological deformation of thermoelastic layered and non-uniform pavements. The task is set to define the intense deformed condition of a road pavement structure as layered half-space during harmonious fluctuation of temperature. It is build the final element model of thermo-elastic deformation of the massif, and made computer analysis of the system. The problem about thermoelastic deformations of a pavements is solved in linear statement. Temperature condition of the field on borders of each layer of road pavements structure and boards of the soil were defined by the equation of non-stationary heat conductivity. It is shown the results of the numerical analysis of thermomechanical processes in layers of road pavements at harmonious change of temperature of a surface of a covering for a concrete example of a structure design.
