    Abstract. Calculation of the strength of rigid airfield pavements is performed according to the limit states. The design model of the pavement is a thin plate on an elastic foundation, and the aircraft landing gear is considered as a combination of distributed load and concentrated forces. The article presents the results of the study of the influence of the parameters of the main support aircraft gear on the results of strength calculation of rigid airfield pavements. It is established that when calculating the strength of hard pavements of civil airfields, a previously unknown feature appears. It consists in the fact that the value of the pavement layer thickness can be found that theoretically satisfies the limit state, but is practically unacceptable. This feature is typical for aircraft with a six-wheeled gear, for aircraft with a four-and two-wheeled gear, this feature is not marked. Calculations of the concrete surface under the influence of the aircraft with a six-wheeled gear were performed and analyzed. As a result of the study, it was found that the existing method for calculating the strength of rigid airfield pavements has a significant drawback characteristic for aircrafts with the gear considered. The application of the current strength calculation method for such aircraft may lead to incorrect results therefore, it needs to be corrected.
    Key words: rigid airfield pavement, strength calculation by limit states, bending moment, aircrafts with six-wheeled gear, concentrated force, plate on elastic base.
