Análisis de fisuras y grietas en pavimentos rígidos mediante resistividad eléctrica

Abstract

The good functionality and structural capacity of roads and highways depends on proper planning, design, construction and maintenance; Likewise of the pavement structure and its surface state; the greatest deterioration found in the pavement surface are the fissures and cracks that may adversely affect the structure. The objective of this project is to analyze and identify the different causes of the appearance of these pathologies in the track Zhud - Biblián at kilometer 49 + 500 by the method of electrical resistivity. Resistivity is measured with the Wenner-Schlumberger method it involves the injection of current into the ground through a pair of electrodes and determination by another pair, thus obtaining the distribution of resistivity in the pavement depending on the physical properties of concrete and the arrangement of the armor inside, the distances between the electrodes and the injected current. This methodology is expected interpret the magnitude of the fissures and cracks in the structure of the rigid pavement, obtaining models in two and three dimensions of the place. In addition, you can check if a reliable method for the analysis of fissures and cracks, as it is a non-invasive method for the structure and could help in the maintenance process because of these impairments.
