    This Technical Project was developed with the purpose of implementing a road maintenance plan for the conservation of the wearing course of the AmbatoQuisapincha Road, in order to extend the useful life of the road and provide future solutions. The project began with a georeferenced survey using a tape measure and GPS, obtaining 332 points along the 3200m of the section under study, which helped us to develop a digital model of the survey. The Annual Average Daily Traffic (AADT) was carried out through a manual vehicular count for seven days in a row at intervals of twelve hours a day and obtaining a future design AADT of 5,412 vehicles per day. To determine the types of faults located on the road, the Pavement Condition Index or PCI method was applied, analyzing 17 sections, giving us a result of 47.5, which indicates a regular condition of the road. Likewise, the Bekelman Beam test was carried out, which allows analyzing the static deflections of the pavement structure, obtaining a TYPE I because the characteristic deflections are less than the admissible deflections, the behavior of the subgrade being good. Likewise, for the classification and determination of the behavior of the soil, four test pits were drilled, obtaining CBR values greater than 8, defining a fair to good subgrade. Finally proposing routine maintenance to save the optimal state of the road surface.
