    The road network is a system of roads that facilitates the movement of people and goods. However, there are areas where the road network is in extremely poor condition due to neglect by the relevant authorities. This results in many sectors lacking adequate road infrastructure due to the deterioration of the road surface, which primarily affects the functionality of the roads. Therefore, evaluating the road network in areas such as the Totoras parish, Zone 61, is important to define the areas requiring intervention. This evaluation provides relevant information that will allow for determining the appropriate type of maintenance, based on the severity of the road surface deterioration, thus extending the useful life of the evaluated roads. To this end, three phases of action were established, planned according to the specific objectives to be developed. These phases included activities such as topographic surveying using drones and RTK (Real-Time Kinematic) technology. In addition, a traffic study was conducted using manual vehicle count data and the 30th-hour design time method for calculations. Five laboratory tests were also performed: natural moisture content, particle size analysis, Atterberg limits (liquid and plastic limits), modified Proctor compaction test, and CBR test. Furthermore, the pavement condition was evaluated using the PCI method and complemented with the pavement structure design, ultimately leading to the development of a preliminary budget for the project. The road network assessment was carried out on a total of 11 roads, 8 of which are fully paved and 3 of which have a mixed composition of asphalt and paving stones. A total of 352 defects were identified, 8 of which were sidewalk defects and 3 curb defects. Likewise, the results revealed that patching and service connection failures are predominant in the sector, occurring 130 times, while bulging and subsidence failures, as well as lane/shoulder unevenness, were observed once along the evaluated area.
