The article makes an attempt to theoretically substantiate the need to take into account the increase in the temperature of the asphalt concrete aerodrome covering when the jet jets of aircraft aircraft are re-peatedly exposed to the surface of the coating not only when calculating the thermodynamic stability of the upper layer at a jet velocity equal to or exceeding 100 m / s but also for other operational conditions. This will re-duce the risks of plastic deformation, likely jet erosion, potholes, even at the design stage and apply asphalt mixes with specified properties for the top coat.
Based on the laws of transfer of thermal energy, a theory was devel-oped for calculating the temperature variation on the surface of the coating and the temperature distribution over the depth of the layer, from the effect of gas jets. The depth of heating by the gas jet of the upper asphalt-concrete layer and the factors determining this value are determined.
The theoretical dependences describing the change in the temperature of the surface of the coating from the action of gas jets and the propagation of temperature fields along the thickness of the structure are revealed. The results of calculations of the temperature of the upper asphalt-concrete lay-er of the coating under the action of gas jets and in their absence in various operational and climatic conditions are presented on the example of the Republic of Peru.
