Análisis de sensibilidad de variables para evaluar el desempeño de pavimentos rígidos para aeropuertos, diseñados por el método de la FAA.

Abstract

The following investigation consists in analyzing the sensitibilty of variables in the design of rigid pavements for airports, by varying and combining input parameters related to the quality of materials and traffic characterization. In the case of materials, these were defined according to the provisions of the FAA and the MOP, in order to establish an analysis that meets the needs of the environment, on the other hand the parameters related to air traffic are constituted by the characterization of two airports that supply the current requests for transport in the country. From the sensitivity analysis we will obtain the variables that mainly influence the design of rigid pavements, from which to establish a model that allows to design pavement structures in a practical and reliable way.To evaluate the performance of the designs obtained, analyzes will be applied in an integral manner, for which three study areas were established: structural, economic and environmental. In the case of structural analysis, the stresses and deformations to which the structure is subjected to different depths of the layers were determined; while in the economic analysis a life cycle cost analysis (LCCA) was applied, to determine the costs of the designs determined from the beginning until the end of its useful life, finally for the environmental analysis it applied a life cycle analysis (LCA), where the greenhouse gas emissions of the designs were established. From this integral evaluation, the functionality, safety and sustainability of the proposed designs can be defined with the mathematical model.
