Diseño pavimento flexible con geosintéticos vía 3,0 km cooperativa nuevo Guayaquil hasta Tiwinza

Abstract

The goal of this project is to develop an alternative road that, through the addition of structural reinforcements, increases durability and structural capacity of an urban road located between the Nuevo Guayaquil cooperative and Tiwinza. It is suggested that the use of reinforcement elements can improve the mechanical efficiency of the pavement structure, reduce construction and maintenance costs, and reduce the thickness of the structural layers. This justifies its technical, economic, and social use in areas with low-resistance soil and unfavorable climatic conditions. Topography, vehicle traffic measurements, and soil laboratory tests were used to develop the project, which was carried out following the AASHTO 93 design methodology. Both alternative and conventional structural designs were carried out, considering granular materials, structural reinforcements, and asphalt mixtures. A comparative cost analysis was also performed. It was observed that the reinforced alternative presented a reduction in costs and thickness, as well as an improvement in structural behavior. In conclusion, the proposed solution is feasible from a technical and economic point of view, contributing to the functional, social, and environmental improvement of road development in cities.
