Modelo de evaluación de pavimento rígido para un eficiente mantenimiento de autopistas

Abstract

The research was born due to the lack of models that evaluate rigid pavements on highways that allow efficient maintenance. For this reason, we present as the objective of the research to evaluate the rigid pavement through technical criteria to allow efficient maintenance on highways. To fulfill the objectives, a model was designed using the following methodology: The theoretical and technical criteria were based on a bibliographic review in relation to rigid pavement, with them the evaluation methods to be used were characterized, such as IRI, PCI and electrical resistivity, thus formulating the rigid pavement evaluation model and its respective maintenance in each case. As a result of the application in the case study of the E-25 highway section Bella India - Santa Rosa, in the province of El Oro, the surface condition was obtained through the value of the international regularity index (IRI) where in most of road sections, values less than 3.5 were reached, indicating good and very good conditions, and in short sections, values greater than 3.5 were found, indicating a regular regularity. These values indicate that a severity analysis should be carried out, which are obtained through the index of Condition of the pavement (PCI), where indices higher than 70% were found, which qualifies the state of the road as very good and excellent, whose result through the model expresses that routine maintenance must be carried out. Finally, a structural evaluation was carried out where the road to Arenillas was taken as an alternative, which has cracks and longitudinal cracks between 20 and 30 meters. identified as geological faults, with them it is indicated what type of maintenance carried out such as the sealing of joints or the integral repair of the panel as the best options for road restoration
