In Peru, one of the main problems to promote the development of many remote and poor localities is not having asphalt roads since in most of the soils they do not have the adequate mechanical properties of the subgrade. In the present thesis it is the improvement of the San Rafael - Nuevo Arica highway, Alto Amazonas Province, Loreto Department, which has investigated the effect on the physical-mechanical properties of the soil with two chemical stabilizers most used by different companies in the heading of road construction. 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 sulphated oils, which is their main property to increase the resistance of clay soils. Stabilizers are chemical components that help to improve the resistance properties of the soil, as a proposal for the improvement of the subgrade of the road in question, Comparisons of natural soil and improved soil were made from the results of the CBR test, using data collected from research carried out. The objective of this research is to determine the effect of the application of these additives through their dosages given in their technical sheet to improve the bearing capacity (CBR) of the subgrade of the San Rafael - Nuevo Arica highway. Likewise, compare them to determine which of the two presents a greater increase in the mechanical properties of the soil. For the samples obtained, pits were made along the unpaved road, physical and mechanical tests were carried out for natural soil, in the soil with liquid additives (PROES and CONAID) and in the soil with solid additives (PROES + CEMENTO and CONAID + CEMENTO). All tests were carried out in the particular Soil Mechanics Laboratory, based on Peruvian technical standards. Our results show that the soil is loamy - clayey, according to the SUCS and AASHTO classification. On the other hand, the maximum CBR percentage for the natural soil was 3%, which, according to the MTC, is an inappropriate subgrade. In the case of soil modified with PROES Finally, for the solid additives PROES and CONAID, the maximum CBR percentage is 70% and 58%, which corresponds to an excellent subgrade, it is concluded that both solid additives PROES and CONAID improve the mechanical properties, which taking into account The CONAID additive will be used because less dosage is applied and it is cheaper to stabilize the soils of the San Rafael - Nuevo Arica highway, Alto Amazonas province, Loreto Region.
