Establecer la ecuación que permita determinar la relación existente entre el porcentaje de compactación y el número de pasadas con el compactador, a través del ensayo EPOL, en materiales granulares tipo subbase clase 3 utilizado como material de mejoramiento bajo cimentaciones

Abstract

Abstract:The foundations in cohesive soils of medium to high compressibility are affected by moisture content, they have produced structural failures in civil engineering projects such as buildings, retaining walls, etc.; to avoid these problems, between the natural soil and the foundation level, the use of qualified granular materials are placed, is used as a measure of prevention and control. Technically, the material is defined as "soil improvement", which has a mechanical behavior (resistance), obtained through compaction; commonly this procedure is deficient, affecting the required density degree, added to lack of quality control and the use of complex equipment. This present investigation establishes a correlation between the traditional methods to determine the degree of compaction with the EPOL, for which a test bench was prepared, executing the work that is carried out on site, with the use of manual mechanical equipment, number of passes and determining the percentage of compaction. The results defined that the moisture content of the improvement soil has a very important role, as well as the number of passes and the compaction process to get to the required degree of density.
