Clay shale is a layer of soil that often causes various stability and bearing capacity problems in geotechnical engineering because it weathers readily when exposed to air and water, reducing soil shear strength. The collapse of the National Sports Development, Education, and Training Center (P3SON) project in Hambalang was one of the issues brought on by Indonesia's weathered clayshale. Therefore, it is necessary to stabilize the clayshale. Experts have developed several methods to increase the shear strength of clayshale by utilizing chemicals as stabilizing agents, such as cement, fly ash, active natural lime, and calcium carbonate (CaCO3). This analysis aims to compare the shear strength parameters of clayshale by adding alternative variations of 5%, 8%, and 11% of active natural lime and calcium carbonate (CaCO3) by weight of the original clayshale samples. The triaxial test was used in this research method, and the sample for testing was taken from Hambalang, Bogor Regency. This analysis shows that both of additions increase clayshale's cohesion and soil shear strength. The cohesion of active natural lime is 15% larger than calcium carbonate (CaCO3). However, both of these kinds of additives can be employed as an alternative in soil stabilization because they may improve the value of the shear strength parameter of clayshale.
