The presence of clayey material in road subgrades is a very common problem that has led to a series of solutions over time. Among these solutions, there are stabilization techniques that make use of ashes, depending on their chemical characteristics. These ashes can replace cement due to their pozzolanic properties, making this technique cost-effective and environmentally sustainable.The purpose of this study is to improve the strength characteristics of clayey material commonly found in road subgrades by adding rice straw and wood ashes from artisanal brick kilns. These ashes were chemically analyzed and belong to Type F. The addition is done in different percentages added to the soil, ranging from 5%, 10%, 15%, 20%, and 30%. The analyzed samples were in their natural state, and the experimental samples, with the addition, were tested using the Modified Proctor and CBR (California Bearing Ratio) tests. The soil classification in its natural state was carried out using AASHTO and SUCS standards. Additionally, tests were conducted for hydrometry, specific gravity, and Atterberg limits. The results obtained demonstrate the effectiveness of adding CDL (brick kiln ashes) as they improve the soil's bearing capacity (CBR) and maximum dry density, with the maximum dry density values decreasing. The optimal content of CDL for addition to clayey soil was found to be 20% of the dry soil weight. Economic analysis of the use of CDL for soil stabilization in clayey soils showed that it is more cost effective compared to conventional methods, such as stabilization with cement and lime.
