    This research project is based on the lack of conservation management of the old PanAmerican Highway E35 in the Lasso sector; the road has different anomalies in the pavement, which, if not maintained in a timely manner, would cause inconveniences to the population of the sector. In the study of the structure of the wearing course, a georeferenced survey of the road was carried out with the help of GNSS RTK HI-TARGET V30 equipment, a volumetric traffic count, evaluation of the physical components present on the road, field and laboratory tests to determine the pavement structure and soil composition, and a visual inspection to determine the level of damage to the wearing course and its structural behavior. These analyses made it possible to determine the traffic performance of the road, classifying it as an RI - RII (2) Arterial Corridor. The average CBR was also calculated at 66.6 percent, which classifies it as good, suitable for base use. The soil composition shows a high content of poorly graded sands, a wearing course that is rated as good with an average PCI (Pavement Condition Index) score of 64.65 points. The Benkelman beam shows Type I deflections, which correspond to adequate structural behavior. As a result, a conservation plan for the road is proposed based on the current damages evaluated in the structure of the wearing course, offering solutions for a correct rehabilitation, conservation and maintenance of the road.
