Assessment of the bearing capacity of pavement structures of airport surfaces (maneuvering surfaces and stands) is the ,responsibility of the airport operator. The basic purpose of evaluating the bearing capacity of pavement structures is to ensure surfaces that will allow take-landing and movement of aircraft to be carried out safely and carried out using the ACN PCN method. At the end of April 2022, a new method of evaluating the bearing capacity of the pavement structure, the ACR-PCR method, began to be applied. The new ACR-PCR method of classification of pavement structures of airport surfaces and procedure for calculating the ACR-PCR number harmonized with the procedure for calculating the ACN-PCN number were studied and analyzed in detail within the diploma thesis. As part of the thesis, the method of calculating the ACR (Aircraft classification rating) number for rigid and flexible pavements and the PCR number (Pavement classification rating) number for two methods of calculation, the method of using aircraft and the technical method, is presented. thecontinuation of the paper, the differences between the old ACN-PCN method and the new ACR-PCR method are clearly indicated. The classification of the USS ZL Split pavement structure was carried out, in such a way that the calculation of the ACN-PCN number and the ACR-PCR number was carried out. procedures used as well as the obtained results were analyzed, and appropriate conclusions drawn related to the new procedure for determining the bearing capacity class of the pavement structure of airport surfaces.
