The objective of this research is a comparative study of versions 1.42 and 2.0 of the FAARFIELD software, based on the results obtained from the design and structural life operation modes, both applied to flexible pavement structures. This is relevant since there have been various pavement design methodologies throughout history, each with different implementation methods, making it necessary to verify if there are differences in the results obtained from this latest update. The study is composed of two parts: structural life analysis and design analysis. The structural life analysis involves constructing an experimental matrix of 108 combinations, aiming to calculate standardized coefficients to determine the significance level of each variable involved in the design. Subsequently, a statistical comparison is made using the results obtained from the design and structural life operation modes through hypothesis testing, statistically testing whether the results differ between both versions. Based on the implementation carried out, operational and design recommendations are also generated, considering the values and parameters used in the study, as these correspond to real data from El Loa aerodrome, located in the Región de Antofagasta, which is part of Chile’s primary air traffic network.
