Abstract
El presente trabajo de investigación se basó en buscar una correcta estabilización
del suelo que forma parte de la subrasante del camino vecinal del distrito de Moche por
medio de la adición en reemplazo de suelo en diferentes porcentajes de cenizas de bagazo
de caña de azúcar (CBCA) más cemento portland tipo 1(CP); Siendo la unidad de estudio
el camino vecinal del distrito de Moche, reemplazando un porcentaje de subrasante seco
por una mezcla de CBCA y CP tipo 1 respectivamente. Se realizó el análisis
granulométrico de subrasantes por tamizado según la norma MTC E 107, se determinó el
contenido de humedad de la subrasante según la norma MTC E 108; además se realizaron
ensayos mecánicos dentro de los cuales tenemos: Proctor modificado y CBR tanto de la
muestra inalterada como de la muestra en la cual se adicionó CBCA y CP tipo 1 en
reemplazo porcentual del suelo. El mejor resultado se obtuvo cuando se adiciono CBCA y
CP tipo 1 en reemplazo del 12.5% de suelo en proporciones del 10% de CBCA más 2.5%
CP tipo 1, el cual presentó una mejora considerable con respecto a la muestra patrón, ya
que se alcanzó un valor de CBR igual a 22.93%.
Como conclusión de nuestra investigación se puede demostrar que es conveniente
usar la CBCA más CP tipo 1 para estabilizar el suelo el cual forma parte de la subrasante,
ya que esto es una solución amigable con el medio ambiente, además de sustentable a
través del tiempo ya que se está aprovechando un desecho industrial del cual se tiene
producción continuamente.
This research work aimed to achieve proper soil stabilization within the subgrade of the rural road in the Moche district by employing a combination of varying percentages of sugar cane bagasse ash (CBCA) and Portland Type 1 cement as replacements for the soil. The study focused on the rural road in the Moche district, where a percentage of the dry subgrade was replaced with a mixture of CBCA and Portland Type 1 cement. Granulometric analysis of subgrades was conducted through sieving following the MTC E 107 standard, and moisture content was determined according to the MTC E 108 standard. Mechanical tests were performed, including Modified Proctor and CBR tests on both the unaltered sample and the sample with added CBCA and Portland Type 1 cement as a percentage replacement of the soil. The most favorable outcome was achieved by substituting 12.5% of the soil with a blend of 10% CBCA and 2.5% Portland Type 1 cement, displaying a significant improvement with a resulting CBR value of 22.93% compared to the standard sample. As a conclusion of this research, it can be demonstrated that employing CBCA and Portland Type 1 cement is advantageous for stabilizing the subgrade soil, offering an environmentally friendly solution that is sustainable over time. This method involves utilizing an industrial waste product continuously generated, proving to be an environmentally friendly and sustainable approach.
