    Análisis de las propiedades físico-mecánicas y CBR de suelos cohesivos de subrasante mezclados con partículas de tereftalato de polietileno (PET)

    The purpose of this experimental work is to analyze the physical-mechanical and CBR properties of natural cohesive soils and cohesive soils combined with polyethylene terephthalate (PET) particles, to be used in the formation of subgrade. For the research, 4 samples of natural soil were taken from 3 different points within the Sevilla don Bosco parish in Morona Canton, province of Morona Santiago with a total of 12 samples of cohesive soil, for which the topsoil was removed and approximately 40 kilograms of the natural sample were collected; polyethylene terephthalate (PET) bottles were also collected and crushed at the Proplasticmax S.A. recycling company. Field and laboratory tests were carried out with natural soil samples and soil samples combined with polyethylene terephthalate (PET) particles, determining: soil type, characteristics, physical-mechanical properties, and CBR. An increase in CBR from 8.4 percent to 11.4 percent was observed. The results obtained in the CBR test, together with the results of the vehicular analysis, were used in the design of the structure of flexible pavement and these thicknesses were compared, obtaining a reduction of 5 centimeters in the total thickness of the road structure.
