    In the province of Tungurahua, which is known for its great commercial capacity, and also for being a province located in the center of the country, the road that connects the sectors of Salasaka - Picaihua, is affected by the constant heavy traffic, for this reason it is appropriate to have a specific conservation and maintenance plan or program to mitigate damage to the wearing course and reduce its deterioration. In this project, a conservation plan for the wearing course was designed, where initially a topographic survey was carried out using GPS and a total station. Subsequently, a vehicular traffic study was carried out by locating a twelve-hour vehicle counting station for seven days, and the road was classified as a class I collector road (MTOP). The physical components of the pavement were evaluated using the visual method "Pavement Condition Method (PCI)", where the type of failure and the existing severity were identified. An average PCI of 37.47 was determined, showing that the pavement condition is "Poor". The deflections measured by means of the Benkelman Beam test, made it possible to classify them as Type III deflections. Subsequently, soil samples were taken in situ, to later take them to the laboratory, for the corresponding analysis, where it was obtained that the soil belonging to the area was classified as gravel with silty sand. On the other hand, the design CBR obtained was 21 percent, indicating that it is a "Very good - Excellent" type soil. Taking into account the results obtained, it is proposed to carry out a road rehabilitation. The referential budget to carry out the respective rehabilitation of the road section corresponds to a total of $ 629.741,83.
