This study addresses the deficiencies of granular materials used for road stabilization, particularly in their performance as a bearing layer. The effects of incorporating chemical additives on the physical, chemical, and mechanical properties of the materials in Conchán were evaluated. Initially, the natural characteristics of the material without additives were determined, obtaining a CBR of 35 %, a plasticity index of 17 %, and a soil classification of GC (A-2-4), with an abrasion wear of 32,82 %. These results did not meet the regulatory requirements, which demand a minimum CBR of 40 % and a plasticity index between 7 % and 9 %.
In response, 2 % cement was added, increasing the CBR to 41%. Subsequently, different percentages of Proes (0,1 %, 0,2 %, and 0,3 %) were added, and tests for compression strength, moisture and drying, and wear were conducted. The best results were obtained with 0,2 % and 0,3 % Proes, achieving CBR values of 58 % and 64 %, respectively. Therefore, the optimal dosage to improve the material was determined to be 2 % cement and 0,2% Proes, meeting the regulatory requirements.
