This research topic aims to develop and demonstrate the behavior that the addition of quaternary salts of liquid ammonium will have, as a stabilizer to the granular sub-base material in pavement structures; in this way, different concentrations of quaternary salts of liquid ammonium were added: 0.5%; 1.0%; 1.5% and 2.0% of the dry weight of the material. So that, in this way, the subbase material from the Sencca-Poroy quarry, added with said stabilizer, act together; (Quaternary salts of liquid ammonium) the pavement will be able to dissipate the loads imposed by traffic (vertical forces), contributing to our general objective, which is to increase its bearing capacity (CBR) and thus avoid failures due to permanent pavement deformation in addition to providing the structure a longer service life. The reason why the use of this additive was determined for this research is not only to improve the geomechanical characteristics of the material from the Sencca - Poroy quarry in the city of Cusco, but also for the interest of knowing how it will act in the soil, the quaternary salts of liquid ammonium for engineering purposes. Reason why the present research work proposes to innovate in the technology of pavement structures by adding quaternary salts of liquid ammonium in the sub-base material in order to analyze to what extent the CBR bearing capacity will increase (18.5%) and how the maximum dry density will vary in the subbase when adding the quaternary salts of liquid ammonium as a stabilizing agent. In this way, we conclude that by adding quaternary salts of liquid ammonium in concentrations of 0.5%, 1.0%, 1.5%, 2.0%, considerably increases the values of support capacity and maximum dry density, in relation to the material without the addition of quaternary salts. of liquid ammonia. Likewise, the optimal dosage of concentration of liquid ammonium quaternary salts that must be added is 1.5% of the dry weight of the material, value with which the CBR support capacity reaches its maximum increased, by 18.5% in the same way, the maximum dry density, reaches its maximum increased, by 0.8 gr / cm (1.4%) in relation to the material without the addition of the quaternary salts of liquid ammonium, which will be used in the sub-base shaping processes.
