dc.description.abstractEste trabajo estudia el comportamiento de rejillas construidas a partir de botellas Pet, como alternativa para el mejoramiento de una subrasante. Para la selección de las botellas con las que se ensamblaron las rejillas, se tuvo en cuenta su uniformidad, para que permitiera una mayor superficie de pegado entre ellas. Se hicieron ensayos de carga axial en botellas individuales y en rejillas de 3x3, rellenas el que mayor esfuerTon/cm^2. Una vez definido el material de relleno, se ensayaron rejillas de 3x3 con alturas de 7.5, 10 y 12 cm, en donde se obtuvo un mejor comportamiento con la rejilla de 7.5 cm, alcanzando un esfuerzo de 0.037 Ton/cm^2. Finalmente se ensamblaron dos rejillas, una pegada en forma lineal y otra en confinamiento, aplicando una carga axial sobre un neopreno con área circular, de esfuerzos de 0.041 Ton/cm2 la pegada en forma lineal, y 0.034 Ton/cm2 la pegada en forma diagonal, deformándose unos 5 mm menos la segunda. Comparando los resultados de esfuerzo soportado obtenidos con el esfuerzo que implica la carga permitida en un eje tipo tándem en Colombia, la cual es de 0.0056 Ton/cm^2 con 11 Ton y presión de inflado de llanta de 80 psi, se concluye que en la malla armada con botellas Pet pueden circular hasta camiones tipo C3, sin embargo se recomienda su uso en estacionamientos, y vías peatonales.
dc.description.abstractenglishThis work studies the behavior of grids constructed from Pet bottles as an alternative for the improvement of a subgrade. Also It made an analysis of grids made with polypropylene vessels was carried out. For the selection of the bottles with which the grids were assembled, their uniformity was taken into account, so as to allow a greater bonding surface between them. Axial load tests were performed on individual bottles and 3x3 grids, filled with thick aggregate held in ½ ", 3/8", ¼ "and granular base material, in order to select the material that would yield the best results. In this case the one with the greatest effort was the aggregate retained in ¼ ", reaching an effort of 0.0258 Ton / cm ^ 2. Once the filler material was defined, 3x3 grids were tested with 7.5, 10 and 12 cm heights, to define which of these heights gives better data. A better performance was obtained by the grid of 7.5 cm in height, reaching an effort of 0.037 Ton / cm ^ 2. Finally, two gratings, one of these pasted in linear and one diagonal form, of 7.5 cm high and filled with ¼ "aggregate were assembled and tested in confinement condition, applying an axial load on a circular area neoprene Of 6 "of diameter, and thus to simulate the footprint of a real rim. These grids showed similar results, bearing stresses of 0.041 Ton / cm2, the grid adhered in a linear form, and 0.034 Ton / cm2 the diagonally bonded, deforming approximately 5 mm minus the second. Comparing the results of supported effort obtained with the effort involved in the permissible load on a tandem type axle in Colombia, which is 0.0056 Ton / cm ^ 2 11 Ton with a tire inflation pressure of 80 psi, we can conclude that in the mesh Armed with Pet bottles can circulate up to trucks type C3, since the effort that supports a grate of 7.5 cm of height pasted in linear form is of 0.041 Ton / cm2. However it is recommended to use in parking lots, and pedestrian paths. 3
