Evaluación funcional y análisis económico de una red vial en la parroquia Ricaurte

Abstract

This project was focused on performing a functional and economic evaluation of a road network located in Ricaurte city center. This sector was selected due to the nonconformities of the community in the road’s state and for the importance of it. The road network comprises of paved and unpaved roads, and it has a length of 6761 m. It consists of 27 roads that are divided into: 17 roads with flexible pavements, 3 roads with rigid pavement and 7 unpaved roads. The evaluation methods for the Surface condition utilized in the paved roads were: Windshield Pavement Condition Index, Road form (provided by MTOP), and the PCI, (Pavement Condition Index) and for the unpaved roads: Unsurfaced Road Condition Index (URCI) and Paser- Gravel Roads. Based on the obtained results from the evaluation methods, an optimization of the road network was carried out taking into account factors for each road. It was given a higher priority on the roads in poor condition because they require an urgent intervention. On the other hand, roads that are in a decent condition require only preventive maintenance to avoid their destruction in a near future. All gathered results were utilized in the software HDM-4 to evaluate and create a system in order to manage the road network in the following stages: 1) Data entry of collected information 2) Evaluation of network’s decay and its effects 3) Economic Analysis of the alternatives proposed in the functional evaluation and 4) Outcome Generation Finally, several maintenance alternatives with their cost involved were presented to GAD of Ricaurte with the aim of being analyzed and considered in future interventions
