Análisis técnico del deterioro del pavimento de las concesiones viales de Colombia conforme a los parámetros de evaluación establecidos en los contratos de concesión para la evaluación de modelos del comportamiento de los pavimentos

Abstract

The present degree work is developed in order to establish deterioration curves from the values of the parameters of the State Index (EI) of the concession projects belonging to the first three generations of road concessions in Colombia. The National Agency of Infrastructure (ANI), so analyze, evaluate and predict the behavior of the pavements that have characteristics similar to the curves raised in this project.

The deterioration curves were developed through the classification of the sections of the concessions, based on the calibration * of the model added by the "Windows" method, taking the factors of Climate (Average Annual Average Temperature - TMAP), Average Traffic Daily - TPD and Type of pavement, as a grouping criterion for deterioration curves.

As a result of the work some deterioration models were obtained that represent the behavior of the pavement in a period of time for sections with similar characteristics, evidencing for some cases that the curves show a behavior of improvement and for others of deterioration, in the same way they were obtained of these curves the equations that represent in the behavior of each parameter, obtained under a linear regression analysis.
