Diseño vial para ampliación, rectificación y asfaltado de la vía Lalanshi, que une la vía García Moreno hasta su Iglesia Católica (1.9 km de longitud), parroquia Ilapo, cantón Guano, provincia Chimborazo

Abstract

The present project has a road length of 1.904 km that joins the Lalanshi road and García Moreno street to its Catholic church, which will benefit the inhabitants of the Ilapo parish of the Guano canton, province of Chimborazo; they will be able to have an access road in optimal conditions that will improve the quality of life and an adequate economic dynamization of the sector. The project began with topographic studies in situ, from which a cloud of points with coordinates and heights was obtained; continued with the study of vehicular traffic in which it was possible to determine the number of vehicles that travel on the road and project to 20 years, the geometry of the road was designed, obtaining the load stresses to which the flexible road structure will be exposed. Soil samples were analyzed at the UPS laboratory in Quito to determine the type of soil and the quality of the subgrade. In addition to hydrological and hydraulic studies and road signs; which allow obtaining data on maximum intensities for a return period, design flows for the longitudinal and transverse drainage works of the road, and preventive, informative and regulatory signs, providing the user with safety along the length of the Lalanshi road. Finally, the environmental impact study of the road project was carried out, which allows evaluating the physical impacts (water, air and soil), biotic factor (flora, fauna), through the Leopold matrix, in the economic and financial analysis allowed establishing the feasibility of the project through economic indicators such as the net present value (VAN), the internal rate of return (TIR) and the benefit - cost ratio B / C.
