Propuesta de mejoramiento de la avenida Ilaló desde la abscisa 0+000 hasta la abscisa 1+900 ubicada en la comuna de la Tola Chica, parroquia de Tumbaco cantón Quito, provincia de Pichincha

Abstract

This graduation thesis addresses the geometric and structural design for the improvement of a 1.9 km section of Ilaló Avenue, located in the Tumbaco parish, which connects the Tola Chica and Plazapamba communities. Currently, the road features an artisanal cobblestone pavement in an advanced state of deterioration, with structural failures such as potholes, depressions, and material loss. The design is based on the current regulations of the Ministry of Transport and Public Works (MTOP) and the Ecuadorian Road Standard (NEVI-12). To this end, a detailed topographic survey was conducted. The traffic study projected a final design AADT of 249 vehicles, classifying the road as a Type IV Collector road. The geotechnical analyses classified the subgrade soils as sandy clays and silts (CL, ML) according to the USCS system and as A-6 and A-4 under the AASHTO classification. Based on heavy traffic, the Equivalent Single Axle Loads (ESALs) were calculated, resulting in a total of 1389920,07 for the design period. As a solution, a 7.20-meter-wide road section was designed, adopting a design speed of 60 km/h. This comprehensive project aims to ensure the road's functionality, durability, and safety, improving connectivity and promoting the community's social and economic development.
