Análisis de los cambios en las propiedades mecánicas de materiales de subrasante por la adición de materiales poliméricos reciclados

Abstract

Introduction: This review is a compilation of several researches. However, it is based on a thesis called “Análisis de la resistencia y durabilidad de un suelo cemento adicionando material no biodegradable polietileno malla Raschel (polisombra) reciclada en diferentes porcentajes en relación con el peso del suelo”, that was carried out at Universidad de La Salle in 2016. Problem: The identification of the variations in the mechanical properties of materials of subgrade by the addition of polymeric materials. Objective: to compile the main research on the modifications of subgrade properties through the addition of natural and synthetic fibers, in order to have a theoretical basis that justifies the application of these additions at constructive level. Methodology: Relevant references compilation referring to the modification of subgrade with polymers and the evaluation of the change in his mechanical properties, synthesis, and discussion of results. Result: 65% of the investigations correspond to studies on changes in compressive strength, 30% of them are directed to focused studies to study the efforts of traction’s answer when they are polymeric fibers, and the other 5% evaluates properties as the fatigue or resistance to the axial tension. Conclusions: A considerable increase in the resistance of compression is denoted, which changes according to the type or material to mixing with the soil and cement. Originality: This article presents the substitution of raw materials of the subgrade with recycled natural or synthetic fibers. Limitations: There are few researches made with natural fibers, so it is limited to the information found.
