    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

    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.

    Implementación del proceso de conservación de la estructura de la capa de rodadura de la vía Patate – Píllaro en el tramo de la abscisa 11+400 hasta 15+320 de la provincia de Tungurahua

    In the present experimental work, a plan for the conservation of the structure of the tread layer of the Patate - Píllaro road is proposed in its 3,920 m of study. A georeferenced survey of the road section under study was carried out, in which an abscissa was considered every 20 m, data were recorded with the GPS satellite receiver, obtaining an amount of 590 points with their respective coordinates, data that allowed the digital model to be made of the track. The vehicular traffic that circulates on the road under study was analyzed, analysis that allowed classifying the road in class II and collector because it receives the traffic of the neighborhood roads. Through the application of the PCI methodology, a section with 17 sampling units was evaluated, whose average value of PCI was 77.82, which corresponds to a very good road classification, which implies maintenance on the road surface. The measurement of the deflections was carried out with the Benkelman beam, for which 20 stations were determined every 200 m along the track, resulting in a type I deflection, which means a good structural behavior of the pavement and the subgrade. 4 openwork calicates were made to perform the tests and determine the type of soil. Edge, gravel and sand type soil has a CBR greater than 30 percent which is used as a subbase, while fine sand and silty soil materials are used as a subgrade.
