Software Tools for Airport Pavement Design
In recent years, civil aviation has experienced intense growth. To meet this demand, a new generation of aircrafts has been developed, with more com-plex landing gear configurations and higher total gross weight. Therefore, new challenges were created for the design of airport pavements. In this sense, software tools were created to meet this need. So the focus of this paper is to understand how this computational capac-ity has been applied in the design of airport pavements. To do this, this writ-ing addresses the evolution of design methods, their formulations, how these methods are applied, and finally, what is the state-of-the-art for the software tools for airport pavement design. For the development of this text, the software FAARFIELD (USA), Alize-Airfield (France), APSDS (Australia), and PCASE (USA) were evaluated. Finally, it was concluded that the main airport pavement design software has similar formulations and methodologies. In general, these applications apply layered elastic methods, with little variations and adaptations to the different existing normative standards. Also, some applications apply finite element methods to their design steps.
