    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil., 2025-02) Medina Bustos, Fabian Mauricio; Cañizares Proaño, Byron Genaro
    Currently, the roads in the sector under study show deterioration of the road infrastructure and lack of maintenance in the urban area, seeking to evaluate the current state of the roads as it impacts the mobility and quality of life of the inhabitants of the Pasa parish in the Ambato canton. In this project, georeferenced data collection was carried out using a global positioning system (GPS), complemented by a visual analysis of the road infrastructure failures. Technical sheets were used to collect the necessary information and determine the state of the roads using the pavement condition index (PCI) method, identifying the level of severity of the failures and evaluating the quality of the tread layer. The evaluation was carried out by visual inspection of the tread layer, using georeferencing techniques and the ASTM D6433-03 regulations, the Ecuadorian Road Standard and the article "Pathology of Articulated Pavements" as references to identify and categorize the irregularities. The Pavement Condition Index (PCI) was used to determine the condition of the roads and propose road maintenance strategies. The study hopes to improve the quality of life of the inhabitants and provide a database to the GAD Municipality of Ambato in collaboration with the Technical University of Ambato. The focus is on developing a road maintenance plan due to the lack of planning, by collecting data from zone 40. This analysis resulted in a set of failures in two types of pavements, flexible and articulated, presenting three types of severity, this was reflected in the database obtained with the record of the failures found. Additionally, a reference budget was prepared for each road, taking into consideration the necessary items for the maintenance and repair of roads, sidewalks and curbs within the study area.

    This technical project arises from the need to provide improved roads, safe and comfortable mobility to the inhabitants that covers between the abscissas 14+625 to 19+500 of the city of Píllaro. In addition, with the objective of reducing vehicular travel time and promoting economic development and tourism in the areas involved and their surroundings. The project was divided into three phases. The first consisted of field activities, such as the delimitation of the area and the topographic survey. A traffic study projected for 20 years was also carried out to establish the geometric characteristics of the road. In the second, soil samples were extracted that were analyzed in the laboratory to determine their physical and mechanical properties. Concluding with the optimization of the road following the indications of the MOP 2003 regulations, the calculation of the pavement structure and the preparation of a reference budget for the project. As a result, a total length of the road of 4,712 km was determined, with an undulating relief and not so steep slopes. In addition, a future TPDA of 4387 vehicles/day was projected, which classified the road as Class I. Subsequently, a sandy-silty soil with low moisture content and a design CBR of 20.70 percent was identified, indicating excellent quality for use in the subgrade. Based on this data, the pavement thicknesses were calculated, which were 7.5 cm for the asphalt layer, 15 cm for the base, and 20 cm for the subbase for the pavement structure. Finally, a reference budget of $1,899.616,41 was made for the execution of the project. This proposal will seek to improve connectivity and reduce vehicle time with adequate planning for the development of the technical project, thus contributing to the economic and social growth of the sector.

    The project is located in the parish of San Fernando, having its origin in the sector of Calamaca and its destination in the reservoir of Chiquiurco, because it is an empirical way presents the lack of drainage works of major and minor art. For this reason, the project was divided into three stages. The first consisted of a topographic survey and hydrological studies, obtaining data from the meteorological station of the Chiquiurco reservoir from 2013 to 2024, in order to determine the maximum flow rates. The second was based on proposing the locations and dimensions of the surface and crown ditch, culverts and bridges, with the objective of complying with the parameters established by the hydraulic design standards for road works. Finally, the third was based on determining the items and unit prices of the project. The result of the maximum intensity of the site was 47.51 mm/h, so the maximum flows in the area were subsequently calculated, obtaining a total of 17 culverts for the entire road with a dimension of 500 mm in diameter, while for the surface ditch a triangular shape was proposed with a dimension of 0.63 m at the base and 0.20 m in height. For the crown gutter, a rectangular shape was proposed with a dimension of 0.30 m base and 0.20 m height.
