    Implementación del proceso de conservación de la estructura de la capa de rodadura de la vía alterna Patate-Baños en el tramo km 2+350 – km 4+700 de la provincia de Tungurahua
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2020) Chicaiza Carchi, Darío Bolívar; Acosta Lozada, Rodrigo Iván
    In the present study of the Patate-Baños alternate track at km 2 + 350 to km 4 + 700, the processes to determine the state and conservation of the structure of the rolling layer, which is located in the province of Tungurahua, Cantón Patate. To begin the development of this experimental project, a topographic survey was first carried out which provided the recognition of the section of the road, to obtain detailed information on the same in terms of width, the existence of roadside ditches, lane width and Everything related to the physical part (Topography), then the number of vehicles that travel on the road for a full week for 12 hours per day was counted and thus determine the Annual Daily Average Transit (TPDA). With the topographic survey information, the Pavement Condition Index (PCI) test was continued, in addition to the Benkelman Beam test, the results of these tests allowed to obtain the current road conditions, both surface and structural, and to corroborate the results, the soil tests (CBR) were carried out, which also include the liquid limit and plastic limit tests that helped provide the type of soil and its mechanical characteristics, and finally, establish the types of damage to the track and whether or not it is necessary to implement a maintenance plan

    Implementación del proceso de conservación de la estructura de la capa de rodadura de la vía Patate-Baños en el tramo km 0+000 – km 2+350 de la provincia de Tungurahua
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2019) Romero Aldás, Johnny Gabriel; Acosta Lozada, Rodrigo Iván
    The objective of this experimental work is to implement the process of conservation of the structure of the tread layer of the Patate-Baños road in the section km 0 + 000 - km 2 + 350 of the province of Tungurahua, in this way determine a road maintenance plan. To proceed with the preparation of the project, field and laboratory investigations were carried out, in accordance with current regulations such as the American Association of State Roads and Transportation (AASHTO), American Materials Testing Association (ASTM), Ministry of Transport and Works. Public (MTOP) and with bibliographic research, among the activities that were carried out in the present project, the topographic survey of the existing road with precision equipment, the vehicle count (TPDA), the extraction of a pit or open pit was made in each kilometer approximately for these altered soil samples to carry out the respective laboratory tests. The evaluation of the condition of the pavement, by means of the Deflectometry test of the pavement with the use of the Benkelman Beam and the PCI method, by means of which we identify and we locate damages found in the asphalt taking an average of samples. After the development of the aforementioned methods, it was observed that the section of the road is in good condition, so it is indicated that it is necessary to execute a routine and periodic maintenance plan.
