Improvement of methodology of calculation and assessment of transport and operational condition of airfield pavement (on the example of airport pavements of Kyiv and Mykolaiv International Airports)

Abstract

The article presents the results of assessment and forecasting of transport and operational condition of airfield pavements on the example of airfield pavements of Kyiv and Mykolaiv International Airports. Domestic and foreign methods of assessment of transport and operational condition and calculation of airfield pavements have been analyzed. One of the most common methods of qualitative assessment of the transport and operational condition of airfield pavements is the method, the essence of which is to compare the classification numbers of aircraft and the bearing capacity of the pavement at the same strength of the subgrade. The results of calculation and design of airfield pavements were performed on the example of Kyiv and Mykolaiv International Airports using the FAARFIELD program. An alternative design of flexible airfield pavement of Kyiv International Airport is proposed. The engineering and geological conditions of Kyiv International Airport were analyzed in detail. Visual investigation of the surface of the pavements of all elements of the airfield of Kyiv International Airport showed that they have satisfactory transport and operational condition. The classification numbers PCN of rigid airfield pavements of Kyiv and Mykolaiv International Airports and flexible airfield pavement of Kyiv International Airport have been calculated with the help of the FAARFIELD program. PCN of the offered design of a rigid airfield pavement of the «Mykolaiv» International Airport is PCN 70/R/C/W/T. This means that the aircraft of this element of the airfield can perform take-off and landing operations without restrictions. Likewise, aircraft can perform take-off and landing operations without restrictions on rigid and flexible airfield pavements of «Kyiv» International Airport.
