Plan de conservación para la estructura del pavimento de la vía Panzaleo - Mulalillo (Chirinche Bajo) en el tramo de la abscisa 3+500 hasta 7+500 de la provincia de Cotopaxi

Abstract

The purpose of this degree work is to propose a conservation plan for the pavement structure of the Panzaleo - Mulalillo road in the specified section, for which several activities described below were carried out. In the first instance, a topographic survey of the road was carried out, and to establish the condition of the current pavement, the Pavement Condition Index (PCI) method was used, which through visual inspections on the surface identifies types of deterioration, severity and quantity that allow to establish the possible causes of deterioration at the surface level. In addition, to fully and functionally evaluate the pavement structure of the road under study, the test was carried out with the Benkelman Beam, which does not demand many resources and is a non-destructive test, it does not alter the integrity of the system. This test allows to obtain an objective and realistic evaluation of the structural behavior of the pavement since in many pavements the problem lies in terms of its structure; in this way an effective maintenance decision can be made. Likewise, in order to carry out laboratory tests and soil studies, soil samples were collected along the road in the specified section, aware of the fundamental role in the general behavior of the road played by the characteristics and mechanical properties of the materials that make up the different layers of the pavement structure; also considering the effect of traffic and weather conditions to which the road is exposed. Based on the analysis and results obtained according to the established standards, it was concluded that the Panzaleo - Mulalillo road in the province of Cotopaxi is in very good conditions of service to its users and a routine maintenance is proposed.
