    This experimental project analyzed the effect of sugarcane bagasse ash (CBCA) on the properties and mechanical behavior of different types of soils, with the objective of finding sustainable alternatives in soil stabilization through the use of CBCA, thus reducing the waste generated in the sugar industry. Soil stabilization is of utmost importance because all engineering works are supported on the soil, which must comply with minimum parameters that allow building on them. In order to determine the effect of CBCA on the index and mechanical properties of the soil, laboratory tests were carried out on soil samples in their natural state and soil samples with the addition of CBCA at 15, 20 and 25 percent. The results of the granulometry and Atterberg limits tests showed that the soil samples correspond to SM and CL soils, and the results of the Modified Proctor and California Bearing Ratio (CBR) tests revealed that: the inclusion of CBCA causes a decrease in dry density, an increase in moisture content and CBR, with the addition of 25.00 percent of CBCA in a SM soil the CBR value increases by 93.18 percent, for a CL soil with the addition of 19.00 percent of CBCA the CBR value increases by 40.00 percent. Consequently, the results of this research can be used as a starting point in the search for sustainable alternatives in soil stabilization.

    Comparación de la adición de polvo de horno de arco eléctrico y ceniza de carbón en una base granular clase 4 para mejorar sus propiedades índice y técnicas

    The stabilization of granular bases with industrial slag presents challenges, such as variability in physical and mechanical properties and the need for precise dosing. To address this, the influence of adding electric arc furnace dust and coal ash in different proportions to a class 4 granular base was analyzed, with the purpose of increasing the quality of the material and reducing the environmental impact derived from the extraction of non-renewable natural resources by promoting the reuse of wastes. It was carried out by means of a laboratory experimental design with controlled conditions, following current regulations, to measure the fundamental properties that govern a granular base. Among the main results, the use of electric arc furnace dust with a presence of 7 percent; and 15 percent for coal ash influenced the granulometric distribution defining the material as a class 3 base, in addition coal ash allowed cataloging the material as a class 2 and/or class 1A base; the CBR bearing capacity increased its value by 10.03 and 18.44 percent respectively; as regards dry density with values of 2.025 and 2.001 grams per cubic centimeter, suitable for dense materials since the granular base layer must be more resistant and with less deformation capacity. The results of this research can serve as a starting point for the innovation of materials to stabilize the granular layers of the pavement structure.
