Elaboración de una guía práctica para el diseño estructural de carreteras.

Abstract

The present project "Elaboration of a Practical Guide for the structural design of roads" is based on proposing practical solutions for the collection and generation of base information, with the purpose of being able to process it and obtain design parameters that can be entered in the corresponding algorithms to the different pavement design methodologies, for flexible, rigid or articulated. In addition, it proposes possible solutions for the identification and control of problematic soils on which the structure of the pavement will be supported, avoiding possible damage to it. At the same time, it is presented a methodology to determine the proportion of materials to be used in the mixture of a raceway, both asphalt concrete and Portland cement concrete, considering that the materials to be used must meet specifications in their physical and mechanical properties, which have been compiled from regulations in this project. Finally, the procedure for the structural design of roads proposed in the different existing design methodologies has been detailed, considering the corresponding input parameters in each method, in order to present as a final result, the dimensions of each structural layer of the road. The methodologies developed are AASHTO 93 and AASHTO 2008 for flexible pavement, AASHTO 93 and PCA 84 for rigid pavement, and AASHTO 93 and English Method for articulated pavement.
