Diseño geométrico y diseño de la estructura de pavimentos de la vía de acceso a Yunquil desde la abscisa 0+000.00 km hasta la abscisa 4+250.00 km” en el cantón Saraguro de la provincia de Loja”

Abstract

The present work of titling is part of the Inter-institutional Cooperation Agreement to carry out the “Estudios y Diseños definitivos de las vías a la cabecera Parroquial de Yúluc, Uchucay- Sumaypamba-Playas de Sumaypamba, Vía a Yunquil y Vías de la Urbanización de los Precaristas, del Cantón Saraguro, Provincia de Loja”, between the Electro Generadora del Austro, ELECAUSTRO SA Compañy, the Autonomous Decentralized Government of the Province of Loja, the Autonomous Decentralized Parish Government of San Sebastián de Yuluc, the Autonomous Decentralized Parish Government of Sumaypamba, the University of Cuenca, and, on the other hand, the Public Company from the University of Cuenca UCUENCA EP. One of the bases for signing this agreement is the main objective of this degree work "Solving access to the sector called Yunquil", because there is currently no access road to Yunquil. This, in turn, is the problem that the locals have asked the ELECAUSTRO SA Compañy, to be given a solution. ELECAUSTRO is executing the " Proyecto Eólico Minas de Huascachaca " located in the Saraguro canton of the Province of Loja and within the considerations of the project, as well as due to the social responsibility policies of the company, ELECAUSTRO has acquired several commitments with the communities, with the aim of promoting their economic and social development, among which is considered the study of a road to the sector called Yunquil, as a contribution to road infrastructure improvements and boosting the local economy. The general objective has been met, with the development of each of the specific objectives. There are three specific objectives that are each covered in a separate chapter. For example, the topographic study as results obtained the topography in detail on the basis of which the horizontal and vertical geometric design of the road is developed in the following chapter from the abscissa 0 + 000.00 km that is on the road to San Sebastián de Yúluc to the abscissa 4 + 250.00 km in the direction of the sector called Yunquil. And the last specific objective is addressed in another chapter in which based on soil laboratory tests, 3 pavement alternatives are designed. Alternative 1 has been considered a pavement structure design in 2 stages, 30cm of prepared subgrade, 15 cm of base and asphalt surface of 3 inches with a projection of 10 years. The second stage of placing 0.5 inches asphalt surface. Alternative 2 has been considered the pavement structure design of a unique, 28cm of prepared subgrade, 15 cm of base and asphalt surface of 3.5 inches with a projection of 20 years and for alternative 3 has been considered a pavement structure design in 2 stages, 27cm of prepared subgrade, 16 cm of base and a surface of D.T.S.B to protect the rolling layer with a projection of 10 years. The second stage placed a 1" asphalt surface. For each of the alternatives, the recommendation is that superficial evaluations be carried out prior to routine maintenance. Condition inventory every year, and roughness every two years. Structural evaluations, deflections at least every 4 years and asphalt seals every 3 or 4 years. In summary, the scope of this degree project is the elaboration of the basic studies of topography, soils and traffic, as well as the realization of the geometric design of the road and the pavement design
