Abstract
International Civil Aviation Organization (ICAO) published the ACN/PCN method to be a standard publish for the airport pavement strength in 1983. However, until now, there is no complete process of PCN evaluation for airport engineering departments to follow. This research establishes an easily-used PCN evaluation program, which is based on FAA AC 1502/5335-5a and the COMFAA program to. This research uses the concept of the regression formula for maximum edge stress from R805FAA program for rigid pavement model and uses the concept of equivalent single wheel load (ESWL), deflection factor, and CBR design method for flexible pavement model. Both rigid and flexible pavement models are constructed based on the output data from the COMFAA 2.0 program . The pavement models are incorporated with the the standardPCN evaluation process suggested by FAA to establish a comprehensive PCN evaluation process. This comprehensive PCN evaluation process is capable of obtaining the same PCN values as the values calculated by the standard PCN evaluation process suggested by FAA. In addition, this research uses the equivalent thickness method and the reverse overlay design concept to solve the PCN calculation problem about AC overlaid pavement . The research also illustrates the calculation of effective K-values for rigid pavement and the equivalent factors for flexible pavement. Finally, the research investigates the differences between the PCN values obtained from multi-point calculation or representative value calculation. The result shows that the PCN values obtained from multi-point calculation are more reasonable than those obtained from representative value calculation.
