This research aims to determine the variation of a soil stabilized with polyethylene terephthalate compared to one stabilized according to the MTC (lime) standard for the stabilization of the subgrade of the Maras-Moray highway, Urubamba Province of the Department of Cusco, with the purpose of making a comparative evaluation when applying polyethylene terephthalate in one sample and in the other lime, in clay soils with low bearing capacity to obtain improved soils at the subgrade level. The technique with which the data collection was carried out is primarily focused on direct observation in situ; demonstrating in this way that the instruments used are the most appropriate and suggested in the MTC soil and pavement manual, and others with reference to soil stabilization, such as equipment, materials and manual tools. It was carried out in 2 critical and vulnerable sections of the road, where 4 pits were made, both sections present a clay soil very lacking in gravel, with low bearing capacity and a CBR of less than 6%, for which there are two options, improve or change the soil with acceptable quarry material, for this investigation was chosen by the first. It was decided to improve with polyethylene terephthalate, in order to then be able to make the respective comparison with the stabilizer recommended by the MTC (lime). In order to determine the type of stabilizer according to the MTC (2014) “Manual of highways: soils, geology, geotechnics and pavements“. Of the 8 types of stabilizers that he suggests, only one is suitable for the characteristics of the soil to be improved, assuming soil - lime stabilization. We carried out a focused investigation with the CBR test in the laboratory of the facilities of the Universidad Andina del Cusco, to determine the optimal dosage of polyethylene terephthalate, in which tables were made, which allowed us to analyze the results of the study. By using polyethylene terephthalate as a stabilizer, it is concluded that they can be used as a subgrade to improve the physical-mechanical properties, with an amount of a percentage of 1.5% with respect to the weight of the soil and also the rectangular geometric shape with dimensions between 5 and 10 mm. In terms of CBR for a soil with low bearing capacity with the presence of polyethylene terephthalate, it increases percentage by an average of 26.5% and lime up to 350%, the expansion in terephthalate decreases by 52.8% and lime by 80%.
