    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.
