Evaluación del comportamiento mecánico de sistemas de GEOCELDA y materiales reciclados (RAP Y CALAMINA)

Abstract

Cellular confinement systems (geocells) improve the conditions and mechanical properties of soils; working together with commonly used granular materials, extracted from quarries. Additionally, due to the environmental impact generated by the treatment of these granules, the reuse of materials from demolition processes has been implemented. This research project seeks to analyze the mechanical behavior of subgrade improvement systems using geocells and a mixture of recycled asphalt pavements (RAP) and Calamine (steel rolling mill). This analysis is carried out by applying laboratory tests in order to find the characterization of granular materials in accordance with IDU regulations. Once the characterization was obtained, the so-called “working formula” was determined, which seeks to improve and complement the physical-mechanical characteristics of a sample of recycled asphalt pavement (RAP) with the addition of calamine. Once the characterization of the materials has been obtained, through the use of the PITRAPAVE software, the modeling of 3 typical flexible pavement structure alternatives in the city of Bogotá is carried out; considering in one the use of the proposed improvement system (geocell in conjunction with the obtained "work formula"). The foregoing, with the aim of obtaining comparison parameters (vertical, lateral and deformation stresses), which in turn will provide us with criteria to determine if the set works optimally. Finally, a presupstantial analysis and execution times are carried out; In order to determine if it is feasible or not, implement the geocell, RAP, Calamine system in engineering activities.
