Abstract

The objective of the study is to evaluate the impact of New Large Aircraft (NLA) on airport flexible pavement versus overloading in ICAO Practice. The study is conducted using Hurghada, Egypt Airport air fleet composition at four annual departure levels, four standard subgrade strength categories, and adding NLA at five different percentages. On the basis of the results of this research, it is concluded that, The statement in ICAO Practice “the annual number of overload movement should not exceed approximately 5 per cent of total annual aircraft movement” must be re-evaluated due to many factors as new large aircraft type ,annual departures and soil characteristics which High reduction in pavement life that has an average of 8.2% of 20 years design life due to introduction of A380-800 by 5% of annual departures, occurred at 3% CBR ., and The statement in ICAO Practice “For flexible pavement occasional movement by aircraft with Aircraft Classification number (ACN) not exceeding 10 per cent above the reported Pavement Classification number (PCN) should not adversely affect the pavement” must be re-evaluated because there is no restriction for adding new large aircraft with 5% Annual departure at any annual departures, soil characteristics comparing between COMFAA 2,3 software which High reduction in pavement life that has an average of 8.2% of 20 years design life due to introduction of A380-800 by 5% of annual departures, occurred at 3% CBR.
