    Pavement structural evaluation is crucial to ensure the durability and functionality of transportation routes. This study focused on the structural evaluation of the pavement of the San Juan Road, which connects several communities in the Santiago de Píllaro Canton, province of Tungurahua, Ecuador. Various methods and tests were used to determine the real conditions of the pavement and propose improvement solutions, the PCI condition determined that more than 50 percent of the road is in poor condition, the deflection method with the Benkelman beam indicated that the 80 percent of the road needs reconstruction; The excavation of 4 pits every 500m was carried out, obtaining 70kg of soil that was used in the laboratory tests, determining that the subgrade is in good condition while an improvement is needed in the Base and Subbase; For the design of the pavement structure, a design CBR of 19.82 percent was calculated with a 75 percent percentile, a future traffic of 1590 vehicles/day was calculated, the road was categorized as class II, in the same way it will be built with a 10 cm class II Base and a 15 cm class II Subbase with a 5 cm thick asphalt layer As a result, horizontal and vertical signage will be placed with the general cost that the maintenance of the San Juan Road will require with a length of 4.5 km and a lane width of 6m.

    Plan de conservación de la estructura del pavimento de la vía que une el barrio San Jacinto con el barrio Huapante Grande de la parroquia San Andrés del cantón Píllaro, provincia de Tungurahua

    The study highlights the importance of maintenance and conservation of the flexible pavement on the road that connects the San Jacinto and Huapante Grande neighborhoods in the San Andrés parish, Píllaro canton, province of Tungurahua. This road is affected by physical (lack of drainage, cracks, potholes, among others) and environmental agents that diminish its service capacity, affecting the mobility of users and in turn the productivity of the sector. To address this problem, field and laboratory studies were carried out to identify structural failures and propose viable solutions. Initially, a traffic study was carried out to determine both current and future traffic, classifying the road as a Type I collector. Through the PCI method, the current condition of the pavement was evaluated, classifying it in the Regular range. In addition, through the Benkelman beam deflection test, it was found that the road infrastructure showed significant damage to the asphalt layer and subgrade, classifying it as Type IV, indicating the need for a complete reconstruction, for which soil samples were taken every 1000 m along the study road to determine its classification and determine the design CBR. Based on the results obtained, the pavement structure was designed to include a 5 cm asphalt layer, a 10 cm class III base and a 20 cm class III sub-base. Finally, a reference budget of $785,958.08 was prepared, based on detailed technical specifications and items.

    Diseño de la vía Atipillahuazo, desde la vía fundadores del cantón hasta la calle Bolívar y la intersección de la vía Atipillahuazo hasta la intersección de la vía Cochaló del cantón Píllaro en la provincia de Tungurahua, con la finalidad de mejorar la conectividad vial de los sectores mencionados

    Given that the road is in poor condition, this project is proposed trying to improve the quality of life of the inhabitants of the sectors, where the respective topographic survey was carried out with RTK equipment, the road traffic count, (TPDA), which was done for a week, from Monday to Sunday with an interval of 12 hours, where it was determined as a Type IV Road, a local road, as stipulated in the MTOP regulations. The respective soil study was also carried out, where pits were made every 500 m of the projected road, in order to carry out tests such as: Moisture Content, Granulometry, Atterberg, Proctor and CBR limits, of each one of them. they took 10 samples where the most critical value was taken for a detailed example, later the respective plans and referential budget were made. By having the design of the road, vehicular and pedestrian traffic will flow more quickly and safely, reflecting the benefit in the families of the sector, which will help in reducing the time for the displacement of the inhabitants, optimizing their social and economic condition. and progress will be achieved in the socioeconomic aspect of the sector, because the area is highly productive in milk and vegetables.
