    This paper develops a road maintenance plan for the section between Redondel La Patateñita and El Mirador, in the canton of Patate, province of Tungurahua, with the aim of assessing the current condition of the pavement and proposing a technical alternative that guarantees its functionality and durability. The research was structured using a quantitative approach, combining field and laboratory procedures, in accordance with the guidelines of ASTM D6433 and the AASHTO-93 methodology. In the diagnostic phase, a topographic survey was carried out using RTK technology and a drone, complemented by a vehicle traffic study, which yielded an Average Annual Daily Traffic (AADT) of 1,768 vehicles/day. Using the Pavement Condition Index (PCI) method, the results showed values ranging from 29 to 84, placing the pavement in “Fair” to “Very Good” condition, with an average of 63.14, corresponding to a “Good” condition. Laboratory tests on grain size distribution, Atterberg limits, modified Proctor, and CBR determined that the soil is silty sand (SM) with low plasticity and an average CBR of 10%, classifying the subgrade as having “Fair to Good” bearing capacity. These results served as the basis for the structural design of the flexible pavement, whose proposed package consists of a 5 cm asphalt layer, a 20 cm granular base, and a 20 cm subbase, reaching a total thickness of 45 cm. Periodic maintenance and selective rehabilitation of critical sections are actions to preserve the pavement's lifespan and optimize the use of available economic resources. The reference budget of $700,725.00 includes the costs of materials, labor, and equipment, based on updated prices from the Chamber of the Construction Industry (CAMICON) magazine.
