In Peru, one of the main problems to promote the development of many remote and poor localities is not to have paved roads since in most of the soils they do not have the adequate mechanical properties of the subgrade. In the present thesis the effect on the physicalmechanical properties of the soil with two chemical stabilizers more used by different companies in the field of road construction has been investigated. The additives to be studied are PROES and CONAID, produced by the companies PROES PERU SAC and TDM Grupo, respectively. These products are stabilizers based on sulphonated oils, which is their main property to increase the strength of clay soils. The objective of this research is to determine the effect of the application of these additives through their dosages given in their technical specifications to improve the bearing capacity (CBR) of the subgrade in the access road to the Barraza Town Center, Laredo. Also, compare them to determine which of the two has a greater increase in the mechanical properties of the soil. For the samples obtained, posts and pits were made along 6 km of the non-paved road, physical and mechanical tests were carried out for the natural soil, in the soil with the liquid additives (PROES and CONAID) and in the soil with the solid additives (PROES + CEMENT and CONAID + CEMENT). All the tests were carried out in the Soil Mechanics Laboratory of the Universidad Privada del Norte, following the Peruvian Technical Standards. Our results show that the soil is limo-clayey, according to the SUCS and AASHTO classification. On the other hand, the percentage of maximum CBR for natural soil was 3%, which, according to the MTC, is an inadequate subgrade. In the case of soil modified with the liquid additives PROES and CONAID, the percentage of maximum CBR is 13% and 10%, which corresponds to a good subgrade. Finally, for the PROES and CONAID solid additives, the maximum CBR percentage is 70% and 58%, which corresponds to an excellent subgrade. Finally, it is concluded that both PROES and CONAID solid additives improve the mechanical properties, which taking into account that the CONAID additive will be used for applying less dosage and is cheaper to stabilize the access road floors to the Poblado Center, Barraza.
