Implementación del proceso de conservación de la estructura de la capa de rodadura de la vía Montalvo Cevallos en el tramo KM 2+400 al KM 5+800 de la provincia de Tungurahua

Abstract

The objective of the research project is to implement a road conservation management system related to the pavement structure of the Montalvo - Cevallos in the section Km 2 + 400 to Km 5 + 800, since there is evidence of deterioration of the rolling, that is to say, the existence of a management system that would provide safety for road users is not reflected. For the evaluation of the pavement structure the method of the Pavement Condition Index (PCI) was used by means of a visual inspection, determining the values according to the type of failure presented at the asphalt folder level with a High, Medium and Low severity allowing to know the current state of the road, later using the non-destructive Benkelman Beam Test (deflections), the plan for reinforcing the pavement structure was developed, since it allows us to obtain real data on the behavior of the layers that make up the pavement structure. are: Base, Sub-Base, Subgrade. To compare the data, samples were extracted from each of the layers and used for laboratory analysis using Granulometry, Consistency Limits, Modified Proctor Density and CBR Compaction tests, resulting in the mechanical characteristics of the materials that make up the material. the structure of the pavement. By means of the traffic count, the equivalent axes were determined to be used for a later pavement design analysis and allowing to reach a reinforcement of the structure of the Montalvo - Cevallos road in the Abscissa K2 + 400 to K 5 + 800.
