Diseño de la calle “Brasil” ubicada en la ciudadela Las Dunas, Cantón Salinas

Abstract

This thesis addresses the road design of Brasil Street, located in the Las Dunas neighborhood, Salinas canton, with the aim of improving mobility, safety and accessibility conditions for the benefit of the local population. Special emphasis is placed on the quality of life and social well-being of the area's inhabitants. The project analyzes key concepts such as geometric road design, flexible pavement design, topographic survey and soil and traffic studies, following the regulations of the Ministry of Transportation and Public Works (MTOP) and AASHTO-93. The topographic survey allowed to identify the physical characteristics of the terrain and its slopes, while the traffic study determined an Annual Daily Average Traffic (ADAT) of 803 vehicles, mostly light. In addition, soil studies revealed that the predominant materials are non-plastic silty sands, classified as SM and A-3, with a California Support Index (CBR) suitable for the required pavement strength. The geometric design, developed with AutoCAD Civil 3D, considered parameters such as design speed and alignments to ensure safe and efficient traffic. The flexible pavement design, based on the AASHTO-93 method, includes a 5 cm asphalt layer, a 15 cm granular base, and a 15 cm subbase, optimized for a 20-year service life under the projected traffic conditions. The rehabilitation of Brasil Street not only improves connectivity and reduces vehicle maintenance costs, but also boosts the urban and social development of the sector, guaranteeing a durable and functional infrastructure that improves the quality of life of residents.
