Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2025-02) Guashca Tocumbe, Alex David; Aldás Sánchez, Milton RodrigoThis Technical Project focuses on addressing the needs faced by the inhabitants of the Juigua Yacubamba, Juigua Rayoloma and Juigua La Playa communities, who are dedicated to agriculture and livestock. The main objective was to improve the road infrastructure in order to provide safe circulation, reduce travel time and promote the socioeconomic development of its inhabitants. The project was structured in three specific phases based on the objectives set. The first included field activities, such as field recognition, topographic survey, vehicle counting and the extraction of soil samples through test pits. In the second phase, the geometric design of the road was carried out, taking into consideration the parameters established by current regulations, including the horizontal and vertical design, as well as drainage works, slope and pavement structure. Finally, the third phase focused on the preparation of the reference budget using qualitative and quantitative research as a baseline. Based on the results, an existing mountainous relief was determined and a Third Class collector road was classified with a silty sandy soil which is optimal for use as a subgrade. The pavement structure design is composed of 5 cm thick asphalt, 10 cm thick class 3 base and 20 cm thick class 4 subbase. Finally, in order to know the feasibility of the work by detailing each of the items with their respective work volumes and technical specifications, a reference budget of $1,232,337.07 was estimated. This investment will improve connectivity between the communities and the urban area, promoting economic growth in the communities.Item Optimización de la geometría de la vía desde el puente Yanayacu hasta Píllaro entre las abs 9+750 – 14+625 perteneciente a la provincia Tungurahua(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2025-02) Caisaluisa Aimacaña, Lady Jazmin; Aldás Sánchez, Milton RodrigoSocial development and road safety are closely related to the quality and functionality of the road infrastructure, which must meet the appropriate technical requirements. This technical project focuses on addressing the challenges associated with the growth of vehicular flow on the Pillaro road, proposing a comprehensive solution based on the optimization of its geometric design. The main objective is to improve traffic conditions and reduce travel times for tourists using this route, thus contributing to the tourism and economic development of the region. In order to meet this objective, fundamental activities were carried out, such as a topographic survey using a high-precision GNSS system, an exhaustive analysis of vehicular traffic, and soil studies carried out in accordance with current regulations. These analyses were essential to determine the physical and mechanical characteristics of the terrain, crucial elements in the formulation of the design proposal. The optimization proposal includes both the geometric redesign of the road and the structural calculation of the pavement, incorporating these elements in an estimated budget and an execution schedule. A total road length of 4.875 km was established, along with a projected annual average daily traffic (ADAT) of 7805 vehicles/day for a design period of 20 years. This projection allowed the road to be classified as a Class 1 arterial road, in compliance with current regulations. As a result, the soil studies revealed a design CBR of 20.31 percent, qualifying the material as highly suitable for use as subgrade. Based on these results, the optimum thicknesses for the different layers of the road were determined: 7.5 cm for the asphalt layer, 15 cm for the base and 20 cm for the subbase, thus guaranteeing the durability and functionality of the road. In addition, a detailed economic analysis was carried out, estimating an execution budget of $1,467,274.83. This investment is intended to improve connectivity between the communities and the urban area, promoting economic development in the region.Item Elaboración de un plan de mantenimiento de la vía comprendida entre los barrios Danzapamba y San José de Barba La y desde la abscisa 5+000 hasta 10+000, cantón Pujilí(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2025-02) Cusco Tucumbi, Kevin Humberto; Bayas Altamirano, Myriam MarisolA road infrastructure designed in accordance with current technical standards is crucial for promoting socioeconomic improvement of territorial connectivity and guaranteeing the safety of users. In this context, the objective of this study is formulating a comprehensive proposal of road maintenance of the road that connects the Danzapamba and San José de Barba La Y neighborhoods. This initiative arises due to the current structural and functional deficiencies pf the road, which compromise significantly improving road safety, vehicle mobility and pedestrian protection. For this purpose, a topographic survey was conducted using RTK equipment and drone. Additionally, vehicle counts were carried out over seven days a week and 24 hours a day. Subsequently, a visual inspection of existing failures was performed using the PCI (Pavement Condition Index) method, where each of the existing failures in the pavement were evaluated. Based on this information a maintenance proposal was developed along with the preparation of the referential budget. The results an TPDA of 3001 vehicles/day and a projected TPDAf of 6792 vehicles/day a 20-year period. Along the 5 km stretch, a total of 44 failures were indefinitely, predominantly longitudinal and transverse cracks, likewise, through laboratory tests, it was determined that the soil is a silty sand through the SUCS classification and granular material of group A-2-4 in the AASTHO classification. For the pavement design, a structural layer with a total thickness of 45 cm was calculated, leading to a referential budget of $685.945,65.Item Evaluación estructural del pavimento ubicado en la red vial estatal E45, entre las abscisas 10+480 y 10+520 del sector de Santa Clara, cantón de Santa Clara perteneciente a la provincia de Pastaza(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2025-02) Brabo Valencia, Hugo Israel; Bayas Altamirano, Myriam MarisolThe eastern region, due to its geographic location in particular, has characteristics that make the road infrastructure susceptible to natural risks such as landslides, settlements, collapses and ground instabilities. These conditions directly affect mobility, generating incidences in the economic and social activities that depend on these road systems; therefore, in this experimental research project, a structural evaluation of the pavement is carried out, through studies of: soils, hydrography and the identification of geological faults, in order to mitigate the risk of accidents caused by the high rainfall characteristic of the eastern area under study. The investigation began with a visual recognition of the study point, observing the geography and topography of the analysis area. During this stage, the presence of a settlement on the roadway could be seen, so the georeferenced topographic survey was carried out, allowing a specific assessment of the relief and shape of the terrain. Likewise, samples were taken for the study of soils by means of test pits, finding a greater presence of coarse material. These samples were later transported to the laboratory where the corresponding tests were carried out to determine the physical and mechanical properties of the collected soil. The presence of geological faults in the road network was also identified. Likewise, the hydrography of the study area was analyzed. As a result of the evaluation, it was concluded that the settlement detected in the roadway is mainly caused by the infiltration of water into the road network between the aforementioned abscissas. For this reason, a channeling system for surface and infiltrated water was designed as part of the solution to the problem, which includes the use of alternative solutions such as the French drain.Item Estudio para el mejoramiento del trazado vial y estructura de pavimento de la vía Mocha-Pinguilí(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2024-08) Toscano Aguilar, Hernan Steven; Núñez Aldás, Galo WilfridoThe present technical project of a road nature originates in response to the vehicular growth experienced by the Mocha-Pinguilí road, which has a direct impact on the geometric layout of the road. Currently, vehicles have difficulties when taking curves that do not have an adequate radius for efficient mobility. Likewise, as this is a commercial route, heavy truck traffic is common, so the current roadway width and pavement structure do not satisfy the growth of vehicles. This project began with a topographic survey using RTK equipment, followed by a traffic study using the 30th hour method. The soil study involved taking samples of the subgrade every 500 meters to analyze its characteristics and properties in the laboratory by means of moisture content, granulometry, Atterberg limits, modified Proctor type B and CBR tests. The geometric layout was made using the Ecuadorian standard MOP-2003, and some suggestions were taken from the standards: Peruvian DG-2018 and AASHTO-2018. The pavement design was developed according to the AASHTO-93 methodology and finally the project's referential budget was made. As a result, an undulating-mountainous relief was determined; the traffic study established a TPDAf of 2,762 vehicles/day and a number of equivalent axles of 1,716,466. A design CBR of 17.72% was determined. The geometric design established a 4-lane roadway and a reference budget of 2'153,849.70Item Diseño de un plan de conservación de la estructura de la capa de rodadura de la antigua panamericana Lasso ABS 317+000 – 322+000 de la provincia de Cotopaxi(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2024-02) Cárdenas Llumitasig, Luigui Fernando; Chérrez Gavilanes, Diego SebastiánThis research project is based on the lack of conservation management of the old PanAmerican Highway E35 in the Lasso sector; the road has different anomalies in the pavement, which, if not maintained in a timely manner, would cause inconveniences to the population of the sector. In the study of the structure of the wearing course, a georeferenced survey of the road was carried out with the help of GNSS RTK HI-TARGET V30 equipment, a volumetric traffic count, evaluation of the physical components present on the road, field and laboratory tests to determine the pavement structure and soil composition, and a visual inspection to determine the level of damage to the wearing course and its structural behavior. These analyses made it possible to determine the traffic performance of the road, classifying it as an RI - RII (2) Arterial Corridor. The average CBR was also calculated at 66.6 percent, which classifies it as good, suitable for base use. The soil composition shows a high content of poorly graded sands, a wearing course that is rated as good with an average PCI (Pavement Condition Index) score of 64.65 points. The Benkelman beam shows Type I deflections, which correspond to adequate structural behavior. As a result, a conservation plan for the road is proposed based on the current damages evaluated in the structure of the wearing course, offering solutions for a correct rehabilitation, conservation and maintenance of the road.Item Diseño geométrico de la vía que conecta las Comunidades Yanahurquito - Chisulche grande - cruz Pungo - San Bartolo desde la abscisa 0+000 hasta la abscisa 3+140 y un tramo de longitud 1.22 km perteneciente a la Parroquia Toacaso del cantón Latacunga, provincia de Cotopaxi(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2024-02) Toapanta Lagla, Fabricio David; Bayas Altamirano, Myriam MarisolThis technical project seeks to solve the problem of the state of the roads in the communities of Yanahurquito - Chisulche Grande - Cruz Pungo - San Bartolo, to have a road in good condition improving time and transportation of agricultural products for marketing and obtaining a better quality of life both socially and economically for the inhabitants. A previous inspection of the place was made to know the topographic conditions of the sector, then the topographic survey was made with a 100 m strip and 20 m abscised in straight sections, and 10 m in circular sections with the help of the RTK GNNS equipment; the vehicle count was developed for 7 days in a period of 12 hours with which the projected TPDA for 20 years was determined. For the soil study, samples were taken with calicatas executed in the field every 1000 m, then moisture content, granulometry, liquid and plastic indexes, modified proctor, CBR tests were performed to determine the physical and mechanical characteristics of each of the soil samples under the AASHTO and SUCS standards; The road geometric design was carried out with the help of the current regulations of the Ministry of Transportation and Public Works (MOP-2003) and from the results obtained in the soil study, the structural layers of the pavement were defined under the AASHTO-93 regulations. Finally, the referential budget was made together with the unit price analysis.Item Diseño geométrico y del pavimento de la vía Llangahua – Silipo – Pinllopata pertenecientes a las provincias de Tungurahua y Cotopaxi en el tramo km 4+000 – 8+000(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2024-02) Chimbana Agualongo, Jairo Eliecer; Moreira Cedeño, Fricson LutgardoThe elaboration of the present Technical Project arises in response to the identified need to establish a connection between the rural communities of Llangahua – Silipo – Pinllopata located between the Provinces of Tungurahua and Cotopaxi, reducing travel times, and promoting the economic and social development of the intervened areas and their surroundings. In this research, the topographic survey was carried out by extracting orthophotos using a drone. A traffic study was conducted by manually counting vehicles in the area adjacent to the project, obtaining a future TPDA of 94 vehicles/day and an equivalent number of axles of 80,833 for the year 2043, defining the road as a Class IV local road. The geometric design was drawn using Ecuadorian MTOP 2003 regulations and suggestions from the Peruvian DG-2014. For the structural pavement design, a soil study was conducted through laboratory tests, resulting in a design CBR of 7.942 percent. Applying the AASHTO-93 Method, thicknesses of 5cm for the asphalt layer, 15cm for granular base class 4, and 20cm for granular subbase class 3 were established. Additionally, horizontal and vertical signage was integrated on the road to provide safety and comfort to the user. Finally, the indicative budget for the project was prepared, establishing items, work volumes, and technical specifications, thus providing a clear understanding of the resources needed for the proposal's execution.Item Diseño de un plan de conservación de la estructura de la capa de rodadura de la vía Salasaka – Picaihua ABS 4+500 – 9+000 de la provincia de Tungurahua(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2023-09) Chávez Pazmiño, Bryan Fabricio; Chérrez Gavilanes, Diego SebastiánIn the province of Tungurahua, which is known for its great commercial capacity, and also for being a province located in the center of the country, the road that connects the sectors of Salasaka - Picaihua, is affected by the constant heavy traffic, for this reason it is appropriate to have a specific conservation and maintenance plan or program to mitigate damage to the wearing course and reduce its deterioration. In this project, a conservation plan for the wearing course was designed, where initially a topographic survey was carried out using GPS and a total station. Subsequently, a vehicular traffic study was carried out by locating a twelve-hour vehicle counting station for seven days, and the road was classified as a class I collector road (MTOP). The physical components of the pavement were evaluated using the visual method "Pavement Condition Method (PCI)", where the type of failure and the existing severity were identified. An average PCI of 37.47 was determined, showing that the pavement condition is "Poor". The deflections measured by means of the Benkelman Beam test, made it possible to classify them as Type III deflections. Subsequently, soil samples were taken in situ, to later take them to the laboratory, for the corresponding analysis, where it was obtained that the soil belonging to the area was classified as gravel with silty sand. On the other hand, the design CBR obtained was 21 percent, indicating that it is a "Very good - Excellent" type soil. Taking into account the results obtained, it is proposed to carry out a road rehabilitation. The referential budget to carry out the respective rehabilitation of the road section corresponds to a total of $ 629.741,83.Item Diseño geométrico para la ampliación de la vía Ambato, agua santa hasta puente Pachanlica, cantón Cevallos, provincia de Tungurahua(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2023-07) Yagual Alarcón, Jessica Andrea; Cañizares Proañ, Byron GenaroIn this project, due to the study in the indicated sectors that are in continuous growth of tourism in the last years, being this part of the economic development of the inhabitants, we proceed with the design and road expansion. For the present project the current conditions of the road were determined, starting with a visual field reconnaissance, then a topographic survey was made with the use of the total station, then the calculation of the Annual Average Daily Traffic was elaborated, with an observation period of 12 hours a day, during seven consecutive days with the objective of calculating the annual average daily traffic, Similarly, 1 cubic meter open-air pits were dug in order to obtain 7 soil samples for subsequent analysis in the laboratory of the Faculty of Civil and Mechanical Engineering, where the physical and mechanical properties of the soil were verified using the SUCS and AASHTO standards. Once the tests were performed, it was possible to obtain the design CBR, which allowed designing the pavement structure, improving the road geometric design and determining the unit price analysis of the project. Once the study is completed, it will be delivered to the GAD of the canton, to be used for the benefit of the community, this will be a contribution of the Technical University of Ambato.
