Some Technical Solutions for the Use of Aerodrome Pavements in the Soft Soil Conditions

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)

“…During operation, under the influence of aircraft loads and natural factors, there is physical deterioration of the surface of the pavement and internal force damage of the airfield structure, which reduces its load-bearing capacity and surface quality [7,8,9,15,16,19,21]. Preservation of the suitability of pavement is the main task of the airport.…”

“…The choice of optimal solutions in the design of airfield pavement structures, bo th rigid and flexible, technologies for their manufacture, construction and operational control necessitates the widespread use of methods of mathematical analysis [7,8,19,21]. Ensuring the reliability and durability of rigid types of airfield pavement is becoming increasingly important in connection with the mass construction and reconstruction of airports in Ukraine and the development of modern aircraft [9,19].…”

“…Premature destruction of concrete and reinforced concrete structures of airfield pavements requires significant investment to strengthen them. The reasons for the premature destruction of rigid airfield pavements are the imperfection of the theory of calculation, which does not allow to fully take into account the real working conditions during operation, as well as, to some extent, the low culture of construction work performance [7,8,15,19,21,22,23]. Variety of soil and climatic conditions, differences in the work of individual structural layers of pavement, and a significant number of factors (temperature and humidity, statistical, acoustic and dynamic loads, vibration) require a very complex analysis in the selection and substantiation of the design of the airfield pavement [7,8,15,16,19,21].…”

To determine the quantitative characteristics of the durability of rigid airfield pavements it is necessary to know the regularity of changing a complex of external and internal factors that determine the behavior of the structure over time.…”

“…To determine the durability of the pavement structure, along with the above data, it is necessary to operate on the reliability characteristics that make up the pavement elements, the types of connections of these elements, and data on the impact of element failures on the reliability of the structure as a whole. Real constructions can be represented by analogues in the form of appropriate mathematical models [7,8,9,15,19,21,22,23]. Ensuring long-term unfailing operation of rigid airfield pavements is associated with certain material costs, so when selecting and substantiating the design of airfield pavements taking into account the specified durability it is necessary to consider not only the cost of the designed pavement but also the cost-effectiveness of extension of service life of the corresponding design.…”
