Evaluación del trazado geométrico en carreteras de montaña en la vía san tintin – porvenir ,cantón Chilla, provincia de El Oro

Abstract

The geometric design of a road is essential to ensure the efficiency, fluidity and safety of its users, while allowing improvements and adjustments, which aim to allow connectivity between the communities surrounding the study site. The main objective of this degree project was to evaluate the geometric layout of mountain roads using technical criteria that allow an efficient road service in the section of Vía San Tin Tin – Porvenir in the Chilla canton, El Oro province. The present study has a quantitative approach, and is experimental in nature where field research methods and bibliographies that are the basis of the proposed model were applied, the techniques used were observation and measurement. For this analysis, the variables under study are: Design of closed curves, operating speed (V85), safety coefficient on curves, speed difference between elements, minimum radius of horizontal curvature and curve superelevation, which we will identify and analyze along the 8.95 km of road. The results of the investigation were obtained from the main characteristics of the sharp curves and the type of pavement, which in this case would be only cement material, with this being able to establish that the current geometric conditions of the road section under study do not meet the minimum requirements of the technical specifications established in the country's regulations. It is concluded that the section of Vía San Tin Tin – Porvenir in the Chilla canton represents a risk for its users due to the conditions in which it is found, so a redesign is proposed in which the radius of curvatures in the data under study is increased, thus reaching the margin to comply with the regulations, and thus benefiting the users of the road.
