The Optimization of ACN-PCN Evaluation Method for Airport Pavement under Operation

摘要

The Aircraft Classification Number-Pavement Classification Number method is the main approach for evaluating the structure of the airport pavement. However, the weakness of exiting methods lies in the difficulty of obtaining the exact PCN of the airport from the Airports Authority. This paper investigated the attenuation behaviors of the pavement structure under the envrionment of aircraft operation, and then the improved evaluation method for airport pavement was presented. The improved method could provide the technical support for accurately judging the bearing capacity of the exiting pavement structure and supply the decision-making reference to the Airports Authority.
