Análisis de reformas geométricas para: Acceso a la parroquia San José de Ayora en el KM 182 de la Panamericana E35; calle La Cantarilla entre av. Pichincha e ingreso a la Comunidad San Esteban; y, acceso a Comunidad San Esteban en el KM 182 de la Panamericana E35 de la parroquia San José de Ayora perteneciente al cantón Cayambe

Abstract

This project's objective is the final engineering design for the geometrical reform at the crossing of Pichincha Ave. and La Cantarilla St., a new variant for the junction of the latter and the former and six transition ramps; these are located in San José de Ayora's north entrance at km 182 of the Panamericana Sur E-35 in Pichincha Province, Cayambe Canton. 2. The project has been developed in three stages. The first stage consisted in basic studies. Surveying was WGS-84 geo-referenced, traffic studies were based on the AASHTO-93 Standard, geological and geotechnical studies under ASTM Standards and Ecuador's Ministerio del Ambiente guidelines for environmental standards. Subsequently, the second stage corresponding to the paving structural design was approached with two alternatives, paved (concrete setts) and asphalt concrete. In this stage were also included the geometrical, hydraulic and traffic signaling plans in accordance with Ecuador's Ministerio de Obras Públicas and AASHTO-93 standards. The third stage consisted in the evaluation and comparison between the two paving methods taking in considerations the quantities of works, unit prices' analysis and investment initial schedules, which lead to the conclusion that the economically most convenient option for the tread layer is sett paved. 3. The construction of these geometric reforms are estimated to benefit the 8860 trips that are made from and to San José de Ayora parish every day, improving travel time of people, goods and services to the surrounding communities, improve the quality of life of La Cantarilla St. neighbors since heavy transport units would use the proposed variant, and, above all, the accident rate will be drastically reduced at km 182 of the Panamericana Sur E-35 due to vehicles entry and exit to Ayora, significantly helping to the future development and well-being of the parish and its people.
