Propuesta de mejoramiento de la calle Manglaralto, tramo comprendido entre la calle Quimag y la calle Teodoro Gómez de la Torre, parroquia la Argelia, cantón Quito, provincia de Pichincha

Abstract

This degree project presents the geometric and structural design for the improvement of Calle Manglaralto, in the section between Calle Quimag and Calle Teodoro Gómez de la Torre, located in the parish of La Argelia, canton of Quito, province of Pichincha. The study section has an approximate length of 2.22 km, and represents an important urban road for communication between residential areas and commercial centers, functioning as an alternate corridor to Pedro Vicente Maldonado Avenue. The scope of the project is to geometrically and structurally design the road in order to improve the road's traffic, safety and durability conditions. To this end, a topographic survey was carried out using a total station and GPS, a traffic study using manual vehicle counts and geotechnical characterization of the subgrade with laboratory tests. The traffic analysis made it possible to determine an Annual Average Daily Traffic (AADT) design of 1556 vehicles, which classifies the road as a Type II road with a collector function according to the Geometric Design standard (MOP, 2003). A total of 893,551 equivalent single axle loads (ESALs) were also calculated for a design period of 15 years. A wavy topographic profile and design values of 90 km/h were used for the geometric design and verification of the horizontal and vertical alignment elements. The structural design of the pavement was carried out using the AASHTO 1993 method, calculating the thickness of each structural layer. In addition, a surface drainage system with drains was proposed for the efficient evacuation of rainwater. Finally, the improvement proposal makes it possible to guarantee a functional, safe and sustainable road, contributing to the improvement of urban mobility and the social and economic development of the La Argelia parish.
