This research work is focused on studying the procedure for stabilizing clay soils with structural lime and determining the optimal stabilizer content that ensures a significant increase in the bearing capacity of the subgrade for the Shucushuyacu - Cuipari Lake - Teniente Cesar Lopez. Structural lime as a stabilizing agent has water absorption properties and improves the strength of clay soils by encapsulating clay particles. In other words, when lime interacts with clay particles, a flocculation effect is produced, creating a diffuse double layer that reduces the potential for swelling and expansion of fine soils and increases resistance to penetration. Granulometry tests, consistency limits, specific gravity, modified Proctor and the CBR test were carried out for soil samples in the natural state and with percentages of 9%, 15% and 21% of lime. Also, the soil classification was carried out using the AASHTO AND SUCS method to complement the necessary calculations. The optimum percentage of lime found was 15%, thereby increasing the CBR value of the soil from 3.3% to 5.9%. In addition, a comparative cost analysis of the pavement structure design is performed. Where, the pavement is modeled on a subgrade in a natural state and another in an improved state with the optimal percentage of lime found. From the results, an improvement in the mechanical behavior of the soil is evidenced by the addition of structural lime, and also that in terms of resistance it is the best stabilization option.
