Análisis de los pavimentos flexibles en la cimentación de su estructura

Abstract

Over the years, cities have been expanding what is needed for better quality roads so that drivers as well as people can move from one place to another in an adequate time and that goods are not mistreated. That is why techniques and methods have been developed for the construction of roads, among which the most used are flexible pavements, that is why in this present practical work of the complex examination we will analyze the structural design of flexible pavement in the city of Machala by the method AASHTO-93. For the design of a flexible pavement it is necessary to know: characteristics of the materials, traffic data and properties of the subgrade, data for the structure of each layer, calculation of the structural number, calculation of the structural layers and the structure of the pavement proposed. According to the MTOP, the main activities for the process are: Traffic study, Determination of soil capacity, Selection of construction materials, Selection of the structure, Construction. An Excel sheet will be used as support to verify the calculations that were delivered to us, as well as a software interface called Equation AASHTO-93. With the help of magazines, scientific articles, bibliography and a comprehensive reading of these documents, it will allow us to understand what are the stages that must be analyzed to design an adequate flexible pavement and that the thicknesses satisfy the expected traffic loads.
