Análisis de sensibilidad de la resistencia al corte en tres tipos de suelos blandos del sur de Quito, combinados con partículas de caucho en tres proporciones sometidos a compactación

Abstract

This paper presents a detailed experimental investigation with the purpose of improving the properties of soft soils by evaluating the sensitivity of shear strength. For the development of the project, recycled rubber particles of different granulometry were initially acquired through an industry and soil samples were obtained from three locations in southern Quito, both undisturbed and disturbed, for experimental analysis, which included the determination of moisture content, granulometry, liquid limit and plastic limit. In addition, modified proctor, direct shear and unconsolidated undrained triaxial tests were performed, with and without the incorporation of rubber particles, in order to evaluate the mechanical parameters. The results obtained were thoroughly analyzed to select the three most promising soil-rubber combinations, which were subjected to the triaxial test. These last results allowed to calculate the modulus of elasticity of the materials studied.
