Qualitative Analysis of Infiltration Water Flow for the Drainage Control of a Flexible Pavement Structure in the City of Bogotá D.C.

Abstract

This article describes the objective, methodology, interpretation and conclusions of a qualitative and experimental analysis to determine the viability of a drainage system that contemplates the inclusion of opened gradations in the pavement structure, and evaluate the improvement on the conventional structure of pavements. 

The methodology used for the development of the research was conducted at different stages. In the first, it was obtained the asphalt layers of the Av. 13A with St. 79, in the sector of the Lake of the Bogotá D.C., then made a tour by the area near the place, with the purpose to make a photographic registry of cases where the study situation appears, with the purpose of selecting a support material that allowed to evidence the phenomenon of possible deterioration of some flexible pavements in the city from the standpoint of internal drainage. As second part, it was made the characterization of the base material, subbase and open base; as third stage, it was built two experimental models: the model of a conventional flexible structure of pavement and the model of flexible structure of pavement with addition of a open base to serve as the internal drainage; finally, it ended with the interpretation and conclusions of the results.
