Resumen
Se realizó el estudio al suelo de la Unidad Vecinal de Indoamérica de la provincia de Lambayeque que presentó un suelo con abundante contenido de limo y arcilla con una plasticidad alta y una baja capacidad portante, necesitando mejorar sus propiedades mecánicas del suelo para así poder ser usado como subrasante de un pavimento. Es por lo que se realizó un análisis del suelo con la fibra de polipropileno y concreto reciclado (RCD-C) ya que demuestran ser es una propuesta viable para mejorar las propiedades mecánicas del suelo. Esta investigación tiene el objetivo de analizar la influencia del concreto reciclado con fibra de polipropileno en las propiedades físicas y mecánicas del suelo arcilloso. Para lograr este fin se
incorpora al suelo diferentes porcentajes de concreto reciclado (10% y 25%) en proporción al peso, más una adición de fibra de polipropileno (0.25%, 0.5%, 0.75%, 1% y 1.25%) de 19mm de largo en función al volumen del suelo conformado. Durante este proceso se evalúa las propiedades físicas y mecánicas del suelo, mediante ensayos de granulometría, contenido de humedad, límites de Atterberg, Proctor modificado y CBR. Según los resultados obtenidos se observa que a medida que la fibra de polipropileno aumenta, el OCH, la DMS y el índice de CBR sigue en aumento. El CBR aumenta hasta un 725% con la dosificación de 1.25% de FP y 10% de RCD-C respecto al suelo natural. Esto indica que se pasó de un suelo no apto para uso de subrasante a poder ser utilizado como tal (CBR?6).
The Indoamérica Neighborhood Unit in the province of Lambayeque has a soil with abundant silt and clay content, high plasticity, and low bearing capacity, requiring improvement of its mechanical properties to be used as a subgrade for pavement. Studies conducted with polypropylene fiber show that it is a viable proposal to improve the mechanical properties of the soil. On the other hand, recycled concrete (RCD-C) not only enhances the bearing capacity of the soil but also makes a significant contribution to the environment by reusing these waste materials. Therefore, this research aims to analyze the influence of recycled concrete with polypropylene fiber on the physical and mechanical properties of clayey soil. To achieve this, different percentages of recycled concrete (10% and 25%) will be incorporated into the soil by weight, along with an addition of polypropylene fiber (0.25%, 0.5%, 0.75%, 1%, and 1.25%) of 19mm length by volume of the conforming soil. During this process, the physical and mechanical properties of the soil were evaluated through grain size distribution, moisture content, Atterberg limits, modified Proctor, and CBR tests. According to the results obtained, it was observed that as the polypropylene fiber increases, the OCH, MDD, and CBR index continue to rise. The CBR increases up to 725% with a dosage of 1.25% PF and 10% RCD-C compared to the natural soil. This indicates that the soil has shifted from being unsuitable for subgrade use to being usable as such (CBR?6).
