Engineers face problems when building roads, runways and airports on soils containing clay, silt and sand, as these are not suitable for pavement design. Soil stabilization is currently carried out with additives and commercial products, being necessary the search for sustainable products such as potato husk ash. The potato is a high production product in Peru, and the potato peel residue is a sustainable option. The samples obtained from a cohesive soil for the research are from the Second Ring Road of the District of Juliaca Province of San Román Department of Puno, for the present research potato peel ash was added in the following percentages: 0%, 10%, 15% and 20%. The methodology applied is through the tests of: granulometry, consistency limits, modified Proctor, specific gravity and CBR, from these tests positive results were obtained for the addition of potato peel ash. Where you can see graphically the interpretation of the results that adding potato husk ash by 20% improves its CBR with respect to the other additions of 10% and 15% taking as reference the standard of Mexico which shows that it is the only one that meets these parameters where it could be said that adding potato husk ash by 20% is optimal, since with this addition we obtain a CBR greater than 20% in the 6 calicatas and its liquid limits in the 6 calicatas do not exceed the value of 40 as the plasticity index does not exceed the value of 12 that are the parameters of the standard of Mexico, complying at the same time with the Peruvian regulations that indicate that for an optimal subgrade, the CBR must be ≥ 6%, in the Peruvian regulations according to the Ministry of Transport and Communications (MTC), "Manual of Roads: Soils, Geology, Geotechnics and Pavements" (Manual de Carreteras & MTC, 2014, p. 40) recommends stabilizing or changing for another material.

Geomaterials comprise naturally formed materials through geological processes, such as soils and rocks, or artificially processed materials, including mineral waste and geosynthetics. These materials find extensive use in geotechnical structures, such as slopes, dams, and pavements, among others. However, two issues commonly arise in earthworks: the materials available in the region do not meet the minimum engineering requirements, resulting in high transportation costs, and the exploitation of new deposits increases environmental impacts. Consequently, there is a need to develop stabilization and reinforcement techniques aimed at creating new geomaterials (NGs) to expand the range of local material applications. In this context, the present study evaluates the key success factors (KSFs) related to the application of NGs in geotechnical structures. The Delphi method was employed through a structured questionnaire developed after an extensive literature review. Brazilian experts from the public, private, and academic sectors were selected to identify the obstacles and potential pathways for the practical application of NGs. The outcomes of the study indicated that the lack of standardization, the complex behavior of geomaterials under varying conditions, as well as technical and economic limitations serve as barriers impeding the widespread adoption of NGs. Finally, a roadmap proposal was devised, encompassing a series of actions intended to facilitate the broader utilization of NGs.
