    Diseño geométrico y del pavimento de la vía LLangahua – Silipo – Pinllopata pertenecientes a las provincias de Tungurahua y Cotopaxi en el tramo Km 0+000 - 4+000

    The current road project arises from the need to establish a connection between the areas of Llangahua, Silipo, and Pinllopata, aiming to create new trade routes that boost educational levels, foster socio-economic activity, and expand markets for local products and raw materials. These actions also aim to reduce poverty, minimize travel times, and lower transportation costs. The technical project began with a topographical survey using a drone, considering the terrain characteristics. Subsequently, a traffic study was conducted, revealing a TPDA of 94 veh/day for a 20-year projection, classifying the road as a Class IV Collector. Horizontal, vertical, and transversal geometric design followed the guidelines of the MTOP 2003 regulations. Soil samples were extracted and laboratory-tested to determine their physical and mechanical properties, identifying a low to non-plastic sandy loam soil with high moisture content and a design CBR of 7.05 percent. These results guided the pavement design in accordance with the AASHTO 1993 standards, obtaining suitable thicknesses considering traffic and soil properties. Finally, the project was quantified, and a reference budget was obtained, subject to changes due to variations in unit prices over time. Nevertheless, it provides an understanding of the necessary resources and facilitates proper planning for project execution.

    Diseño geométrico y del pavimento de la vía Silipo – Pinllopata en el tramo 8+000 hasta 12+000 perteneciente al cantón Pangua de la provincia de Cotopaxi
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2021-03) Manosalvas Paredes, Leonardo David; Moreira Cedeño, Fricson Lutgardo
    This technical project was developed in the province of Cotopaxi, beginning with a walk to recognize the place to observe the characteristics of the terrain prior to carrying out the topographic survey and the equipment that will be necessary to use for this purpose. It was decided to use a drone for the topographic survey due to the characteristics of the terrain that has steep slopes. The vehicle count was carried out for 7 days in a row with a time of 12 hours a day and periods of 15 minutes, this data obtained was used to develop the project and determine based on the count the design and circulation speed and according to this the type of existing track (Class V). Soil samples were also collected to determine the physical and mechanical properties through the tests and determine the type of soil to obtain the thickness that the road will carry. This project is carried out following the norm of the Ministry of Public Works (MOP- 2003), which governs in our country as the Ministry of Transportation and Public Works, complying with this norm, the horizontal, vertical, and cross-sectional design was carried out, adapting the characteristics of the land, adopted speed and other restrictions that the norm dictates. Through the designs, the quantifications of the cut and fill volumes were determined, as well as a referential budget of the complete project which may be subject to changes due to the variation of labor indexes and unit prices.

    Diseño geométrico y del pavimento de la vía Silipo – Pinllopata en el tramo km 12+000 – 16+000, perteneciente al cantón Pangua de la provincia de Cotopaxi
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2021-03) Andrade Barrionuevo, Danny Efraín; Bayas Altamirano, Myriam Marisol
    The present project was carried out in the Pangua canton of the Cotopaxi Province and its purpose is to design an alternative road that connects Silipo-Pinllopata, in addition to the design of the pavement, in order to improve economic, cultural, tourist and social development. of the canton. For the study of the TPDA, a manual count of 7 days was chosen, for 12 hours from 2 to 8 december, 2019. For the geometric design of the road, it was carried out under the norm of MOP-2002 (Ministerio de Obras Pública) and MTOP-2003 (Ministerio de Transporte y Obras Públicas), where the horizontal, vertical and transversal design are suitable for the conditions of the terrain, speeds and restrictions limited in the MTOP-2003 regulation. 9 soil samples necessary to carry out laboratory tests were extracted which are: Granulometry, Atterberg Limits (liquid limit, plastic limit and plastic index), Modified Proctor and California Bearing Ratio (CBR). Through the AASTHO-93 regulation, it was possible to calculate and know the optimal asphalt layer thicknesses for the volume of traffic proposed for a design period of 20 years. Through the designs it was possible to quantify the cut volume, in addition to its total length, therefore, the referential budget was calculated.
