Drenaje y tiempos de saturación en capas de base para pavimento y su interpretación según la guía AASHTO 93

Abstract

In the present research, the permeability of granular soils that will be used specifically as base material is analyzed and discussed, the results of the present study are intended to evaluate this type of base materials, aimed at its future application in terrestrial roads of our country. Samples were taken of material placed as a base of the sectors: "Tunnel of the City of Loja", "Vía Loja - Malacatos", "Vía Loja - Zamora" and their respective combinations of base materials of the aforementioned , Samples were taken from these sectors because these materials were being placed here, from the point of view of road problems, either for the design of a pavement structure or when it is located as a surface or layer Of rolling. The problem is that these soils must have adequate permeability to be placed on site and thus help the design of the pavement to be implemented in these sectors; Since if these bases do not meet the technical standards specified in the Technical Specifications book of the MOP, section 404, the pavement will fail very fast and between them would collapse the work by the formation of bumps.
