The publication presents test results and analysis of the impact of military aircraft on an airport pavement made of pre-stressed panels. Three types of aircraft were used in the experiment, i.e. TS 11 ISKRA aircraft, SU 7 BM aircraft and SU-22 M4 aircraft. In the field tests, geophysical methods were used to measure the dynamic properties of the airport pavement structure. Based on the few vibration measurement methods of this type of construction that can be used, the vibration level of the pavement caused by the aircraft operating on that surface was recorded. The tests were carried out for various levels of aircraft thrust, the degree of harmfulness of the impact of generated vibrations on the pavement by sources of excitement, which were the above-mentioned aircraft, was assessed. Due to the fact that the research was one of the first to be carried out in the country, and such research is rare, there are no publications devoted to this issue also in foreign literature. Therefore, there are no reliable and credible criteria for assessing the impact of vibrations on these constructions. In the assessment of dynamic phenomena, by analogy, assessment methods and criteria related to general construction facilities were used. The most frequently used criteria for assessing dynamic interactions are based on the vibration speed criterion. The publication carried out an impact assessment based on the following criteria: vibrator scale, SWD scale and Zeller scale. Keywords: Aircraft; cement concrete Airfield pavement; Frequency
