Diseño vial preliminar de la calle s34w, en el barrio Buena Ventura, en la parroquia de Chillogallo, cantón Quito, provincia Pichincha

Abstract

The preliminary design of the street "S34W", starts from the topographic survey, vehicle counts and mechanical analysis of soils; in order to carry out the GEOMETRIC DESIGN, ANALYSIS OF VEHICULAR FLOW and PAVEMENT DESIGN. Within the geometric design, a typical section is established for the entire length of the street, horizontal design (corridor) and vertical design based on the parameters established by the MOP2003 Norma de Arquitectura y Urbanismo de Quito, according to its TPDA value. Regarding the vehicular flow analysis, the counts or gauging were carried out at a single point and in a parallel street because S34W street does not have vehicular flow at present. The counts performed in April from Monday to Sunday for 7 days, from 6am to 7pm were completed by probabilistic methods to have 24-hour data and then projected to get traffic in 20 years to calculate the TPDA of the parallel street and project with a decrease to the TPDA of S34W street. With this TPDA value we can classify the street according to the two regulations mentioned above, which for this street the type III and ´´arterial secundaria´´ is the best way. For the pavement design it is essential the TPDA values and the results of the DCP (CBR) tests to determine a pavement conformation based on the results of the calculated structural number and the structural number given according to the proposed pavement conformation. This project also includes a drainage design, signage placement, cost analysis and environmental impact mitigation plan.
