Prerequisites for calculation of the stress-strain state of a layered structure consisting of a pavement concrete slab and an asphalt concrete layer are considered. Leading factors in the development of defects of this structure are marked. Methods for determining tensile stresses in the asphalt concrete layer with due regard for thermal-physical characteristics of the material are proposed. The dependence of the development of deformation of a strengthening layer of aerodrome pavement free from external mechanical impact on the effect of nonstationary temperature field with due regard for thermo-elastic characteristics of the structure material has been established. The dynamics of the change in the stress state of the structure in time and along the depth depending on the thickness of asphalt concrete layer is revealed. The use of methods proposed for forecasting the operating time of the escalating layer on the basis of these changes in asphalt concrete properties is substantiated.
