    The condition and serviceability of a road is one of the fundamental aspects, emphasizing that the current condition is considered regular, requiring the execution of road maintenance. The analyzed road connects an area that contributes mainly to the agricultural, livestock and productive development of the Santiago de Píllaro canton. Initially, the soil typology was analyzed by extracting soil pits every kilometer, the natural moisture content of the soil, granulometry, Atterberg limits, modified Proctor method B and CBR; the current TPDA was analyzed using the methodology of the thirtieth hour, the ESAL deduction that was projected for the design year, using the PCI based on ASTM D4695 and the pavement condition was identified from a total of 14 sample units, identifying that the road had a resultant of 51.21 equivalent to a regular road condition. The resulting deflectometry resulted in the first two kilometers requiring routine maintenance, while the remaining 2.5 kilometers required road rehabilitation based on redesigning the pavement structure thickness. As a result, the maintenance plan included crack sealing and patching in the initial 2.0 kilometers and in the remaining 2.5 kilometers, a redesign of the layers that make up the pavement structures was proposed, obtaining a total reference budget of $ 274 893,095, to improve and optimize the current condition of the road.
