This research evaluated the influence of adding recycled and shredded PET on the stabilization of SW-SM (silty sands) and ML (silts) soils collected in the Baños del Inca district, Cajamarca. The methodology employed was applied and experimental, utilizing Modified Proctor and CBR tests following ASTM and NTP standards. Initially, the SW-SM soil had a CBR of 12.30%, while the ML soil had a value of 9.80%. When PET was added in proportions of 1%, 3%, and 5%, the mixture with 5% PET proved to be the most efficient, increasing the strength of the SW-SM soil to 17.80% (a 44.71% improvement) and the ML soil to 14.10% (a 43.88% improvement).
