The improvement of subgrade soils has been of constant concern to site engineers. This work arises from the need to establish new mixtures that allow stabilizing subgrade soils using properly treated organic materials that guarantee durability and improvement of mechanical and physical properties. It was proposed to evaluate how the addition of Oryza Sativa husk ash and coconut fiber influences the stabilization of clay soils at the subgrade level. In this research, Oryza Sativa husk and coconut fruit residues were used, seeking the optimum percentage of addition to improve the low bearing capacity of the clayey soil. Additions of Oryza Sativa husk ash (4.5%, 8.5%, 12.5% and 16.5% by weight) and coconut fiber (2%, 4%, 5% and 8% by volume) were incorporated. To achieve this objective, the optimum calcination temperature of Oryza Sativa husk ash as well as the chemical composition of the ash of this product were analyzed. Plasticity, compaction and CBR tests were carried out during the experiment. The results showed a decrease in the maximum dry density of clay from 1.83 g/cm3 to 1.63 g/cm3 and in CBR value from 3.83 % to 21.03 %, achieving a 17.2% increase in the CBR index. This allowed the subgrade to be classified as Excellent. Likewise, the optimum percentage of the mixture was established at 16.5% Oryza Sativa husk ash and 8% coconut fiber.
