Abstract

The lack of a rigorous mathematical model of the performance of asphalt layers increase complicates the adoption of technological solutions in the design of structures strengthening of pre-cast airfield pavements. To determine the dynamics of changes in stress-strain state of multilayer airfield pavements it is necessary to conduct numerical simulation of temperature effects on him, generalization of the results of which will determine the optimal characteristics of the coating during reconstruction and to take measures to slow down reflective cracking in asphalt layers build. As a result of the obtained regularity of the deformation reinforcement airfield pavements under the influence of non-stationary temperature field free from external mechanical impact, given the thermoelastic properties of the material of the structure; dynamics of changes of the stress state of structures in time and in depth and evaluated the influence of the thickness of the asphalt layer on the voltage. The data obtained in the settlement process, can be used to design asphalt concrete lay-ers increasing in the reconstruction of runways, prefabricated airfield pavements
