Clay soils, due to their high mineral content, such as illite, tend to be very expansive and present large deformations when loads are placed on the soil, such is the case of this investigation that has as material a clay soil of low plasticity. For this, it was decided to use, as an addition to the soil, expanded polystyrene (EPS) and Rice Husk Ash (CCA) to improve the properties of the soil and its stabilization. In the case of EPS, it is effective for its implementation in clay soils, significantly reducing the pressure that can be exerted on an embankment or hightway, this mitigating failure due to settlement and generating greater stability against slope failures. Likewise, rice husk ash is favorable for stabilizing clayey-sandy soils, increasing the unconfined compressive strength and can expand it up to 247% when the CCA content range is between 0 – 10%. For a correct development of the evaluation and analysis of the proposal, the report was divided into 2 parts: In the first part, tests were carried out to determine the classification and properties of the extracted soil and in the second, the Modified Proctor test and the unconfined simple compression for the 4 proposed samples. Among the main results, it is observed that the shear resistance increases up to 3 times compared to the shear resistance of the specimen without additions versus the specimen with additions. Likewise, it is observed that the specimens with EPS content present greater resistance to flexibility compared to the specimen without these materials. As a contribution to these investigations, we propose the use of two lightening materials to be used in the filling of embankments, these materials are expanded polystyrene beads (EPS) and rice husk ash (CCA). Favorable results were obtained, such as a reduction of 14.34% of the volumetric weight, therefore the settlement will be reduced. Furthermore, it is observed that as the dose of CCA increases, the shear resistance increases.
