    The main objective of this experimental work is to propose a road conservation management system based on the physical characteristics of the road: Cevallos-Quero on the stretch from the abscissa K5 + 800 to the abscissa K9 + 100 of the province of Tungurahua. Mechanical equipment was used in materials testing and soil mechanics laboratories to determine the deflection of the pavement in specific areas of the Cevallos-Quero road, as well as open pit exploration (PCA) to obtain samples for Laboratory analysis: Granulometry, Consistency Limits, Density (Proctor), Abrasion and California Support Value (CBR) applying the standards: American Association of State Highway and Transportation Officials (AASHTO), The Ecuadorian Standards Institute (INEN) ) and the American Materials Testing Association (ASTM). Directly on the road grade, the surface and structural evaluation of the pavement was carried out applying the Pavement Condition Index (PCI) and Benkelman Beam Analysis method to determine the condition index of the pavement, Deflection and radius of curvature of the pavement structure. properties with which the current situation of the tread layer on the track and behavior of the pavement structure was assessed. The reason for the premature deterioration of the road surface is due to the fact that the thickness of the layers of the pavement structure is insufficient, which no longer meets the required quality standards. Therefore, it was determined that it is not feasible to perform a road conservation plan to rehabilitate the structure of the road surface and considering the current state of the road, it is necessary to reinforce the pavement structure on the road: Cevallos-Quero on the section from the abscissa K5 + 800 to the abscissa K9 + 100 of the province of Tungurahua. This reinforcement has a referential budget of $ 650,014.21 without including the value of IVA.
