“…That information could be especially helpful, during the transfer period until the full implementation of the ACR-PCR system. However, it must not be ignored, that this correlation has occurred for the typical materials of the FAA, and deviations from these material assumptions may alter this finding, especially if one considers the limitations of the empirical procedure for PCN determination, as far as the material characteristics of the pavements are concerned [6,15,19]. The issue of the transferability between the two indexes may become even more challenging, taking into account that there are several methodologies that have been developed internationally for PCN determination, that usually produce different results [6].…”

Airfield pavements are important assets that have to secure the safe operation of an airport. On this basis, assessing and reporting the bearing capacity of an airfield runway pavement is a critical task. Recently, the Aircraft Classification Rating-Pavement Classification Rating (ACR-PCR) system has been introduced, which uses the PCR index for expressing the bearing capacity of an airfield pavement. In order to accurately determine PCR, the mechanical characteristics and the thicknesses of the individual layers of a pavement are required. For this purpose, it is not seldom that in the absence of resources dedicated to detailed pavement evaluation procedures, assumptions for the material characteristics of the pavement considering typical materials may be made, while pavement thicknesses may be derived by pavement design records. The present paper highlights the importance of using Non-Destructive Testing (NDT) for accurately assessing the in-situ condition of a flexible runway pavement and determining the PCR index. In order to achieve the goal of the investigation, measurements were performed along the flexible pavement of an airport runway. In addition, the paper focuses on the impact of the variation of the thickness and of the mechanical characteristics of the asphalt concrete layers on the PCR index and on the interpretation of the results considering the acceptance of aircraft operations by airport authorities.
