    Estudio definitivo para el mejoramiento de la vía Cuatro Esquinas – Nitiluisa, parroquia Santiago de Calpi, cantón Riobamba, provincia de Chimborazo
    (2022-09) Caiza Freire, Dennys Oswaldo; Acosta Lozada, Rodrigo Ivan
    The project is carried out in agreement with the GAD rural parish of Santiago de Calpi and the Technical University of Ambato. For the design of this project, international standards such as AASHTO, SUCS and ASTM were used: AASHTO, SUCS and ASTM, and in national standards, were: MOP 2003, NEVI 2012, MOP -001-f 2002 and INEN 2011, based on these, the objectives to be addressed were carried out, such as: traffic count, topographic survey, soil study, geometric design of the road, hydraulic design, pavement design, signaling and budget. The road has a length of 4404.36 meters; according to the traffic count and its respective analysis, a fourth order road was determined, where a total width of 9.20 meters was necessary, including lane width, curbs and shoulders. The topographic study consists of a 40-meter strip width starting from the road axis; for the soil study, borings were made every 500 meters starting from the 0+500.00 km abscissa. The geometric design included: horizontal and vertical design, cross sections, mass diagram and cut and fill volumes. The improvement of this road is a fundamental part for the development of the parish of Santiago de Calpi, since it allows improving livestock, agriculture, tourism and communication between neighboring sectors, as well as providing safety and comfort for road users.

    Diseño geométrico de la alternativa vial Shuyo – Pinllopata en el tramo km 24+000 – 28+000 perteneciente a los cantones Pujilí y Pangua de la provincia de Cotopaxi
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2020-08) Silva Coque, Esteban Fernando; Moreira Cedeño, Fricson Lutgardo
    This project was carried out through preliminary studies since there is no design study on this road, topographic tools and equipment such as the RTK (Real Time Kinematic) equipment were used to obtain the contours of the existing road every 500 meters. In addition, a drone was used that flies over said route for imaging (orthophoto), video and obtaining the topographic strip. A fundamental part of this study was the field survey, which consists of a length of 4000 meters, is currently a ballast road. Subsequently, the topographic survey of the road and the design were carried out horizontally, vertically and transversely according to the regulations dictated by the Ministry of Transportation and Public Works of Ecuador. Then the Annual Average Daily Traffic (TPDA) was determined to know the level of service of the road which is Class IV in the estimated design period of 20 years, the calculation of cut volume of 213680.64 m3 was also achieved Due to the topography of the project and above all meet the requirements for this type of project. Finally, a referential budget was prepared for the construction of this road with optimum performance. Everything is described in this document both in tables, figures and plans duly detailed.

    Diseño geométrico de la alternativa vial Shuyo-Pinllopata en el tramo KM 20+000- 24+000 perteneciente a los cantones Pujili y Pangua de la provincia de Cotopaxi
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2020) Freire Ruiz, Cristhian Dario; Acosta Lozada, Rodrigo Iván
    This document describes the technical process that must be followed in order to propose an appropriate geometric proposal for a road in a mountainous area. It is described step by step what is the methodology to follow the rules that were taken into account and the different variations and considerations that should be taken when performing a pre-feasible process. The first step is to carry out a current topographic survey of the area to be able to have details of contours and dimensions that will be considered in the geometric design of the road, the process that was taken in the present work was carried out with a Drone and taking photographs which are processed to obtain ortho referenced geo photos. In addition, the field work also includes the vehicle count in order to determine the TPDA that is the most important value to consider the different types of roads that the MTOP standard puts us in consideration, and the characteristics that each of them has in terms of speeds spokes and cant. Obtained the field data is processed to the office work, with the topography already digitized we can obtain a proposal of alignment that is considered as the horizontal alignment, which will also contain widths and corners in the curves respecting minimum radii and design speeds, of The same way having the same considerations for vertical and transverse design. Once verified that the design values meet the standard, we can quantify the cut and fill volumes in order to obtain a referential budget that would be an important value to approve or disapprove the pre-feasibility of the project.
