Mejoramiento vial del tramo en 1.5 km de la avenida mariscal sucre, ubicada en el barrio Araque, parroquia San Pablo del Lago, cantón Otavalo, provincia de Imbabura

Abstract

The present work addresses the design and improvement of Mariscal Sucre Avenue, located in the San Pablo del Lago parish, Otavalo canton, Imbabura province. The main objective of the project is to rehabilitate a 1.5 km stretch through the implementation of a flexible pavement, aligned with the regulations of the Ministry of Transportation and Public Works (MTOP), to guarantee road safety and functionality, also promoting economic and tourism development. of the region. The initial study revealed various pathologies on the road, such as cracks, potholes and surface wear, attributable to factors such as the increase in heavy vehicular traffic, adverse weather conditions and lack of maintenance. Additionally, the lack of an efficient drainage system has generated problems of water accumulation and softening of the pavement, aggravating the deterioration of the infrastructure. Based on these findings, a comprehensive intervention is proposed that includes pavement rehabilitation and the implementation of functional drainage systems. The methodology used includes topographic surveys, geotechnical tests and traffic studies. The data collected was used to model the geometric design of the road, including its horizontal and vertical layout, as well as to determine the thicknesses of the structural layers of the pavement using tools such as Civil 3D and AASHTO standards. The calculation of the Annual Average Daily Traffic (APDA) made it possible to project future demands, ensuring that the proposed infrastructure has a useful life of at least 20 years.
