    In this experimental project, the need for the province of Tungurahua to maintain the intercantonal road network is presented, since the people of Tungurahua must maintain the road network in good condition, being a central province in the country, it is key for socio-development. economic, intercommunication and tourism. In the experimental project presented, a georeferenced survey of the roads under study was carried out, where the coordinates were digitized, obtaining a 2D model. Afterwards, a visual study of the road was carried out applying the PCI (PAVEMENT CONDITION INDEX) method, finding 19 different types of failures on the road surface of the roads under study, these failures are in ranges of mild, medium and high. A solution is proposed that helps road conservation with rehabilitation; a modified pavement with PVC (vinyl plochloride) is proposed, where 1, 2 and 3 percent of fine aggregate was replaced by PVC. As a result, it was obtained that the average PCI is 60.34 percent on the Patate – Pillaro road, 71 in Pelileo – Patate, 81 in Quero – Salasaca and 83.5 in Patate – Baños, on the other hand the pavement modified with PVC using the MARSHALL test. for flexible pavements resulted in the addition of this material improving the mechanical characteristics of the flexible pavement with an optimal percentage of AC-20 of 6.5 percent and 3 percent of PVC, obtaining stability and flow values of 4469.21 lb, 13 percent hundred. cent respectively.
