The growth of the vehicle fleet has increased emissions of polluting gases and the disposal of unusable tires, which often end up being burned or in landfills, causing soil and water contamination. Sandy soils often need to be replaced with others that have better geotechnical characteristics, complicating minor traffic projects. This highlights the need to optimize the existing soil to increase its CBR value and facilitate its use in such projects. The use of recycled rubber in construction has led to research suggesting an optimal percentage between 3% and 20%. In this research, 7% was chosen for SP-SM soil and 3% for CL soil, as it improves their geotechnical properties. In this research, an analysis of the data obtained through various physical characterization tests was conducted, including the Proctor test and CBR (California Bearing Ratio), where the results indicated that the type of soil is poorly graded sand with silt, classified as A-3/SP-SM according to current regulations. One of the main problems with this type of soil is its low bearing capacity and lack of adhesion between its particles, resulting in minimal direct shear resistance. This is crucial for the construction of structures on these grounds. The research highlighted that the use of recycled rubber powder improved the CBR of the soil by 27%. This method was chosen for its excellent results in similar studies, ease of obtaining rubber powder, and contribution to the soil's strength index (CBR). Additionally, conventional stabilization methods such as lime, cement, and asphalt have conditions that do not adapt well to sandy soils.
