Caracterización de bancos de préstamo localizados en la ciudad de Loja, para aplicación en obras de infraestructura vial

Abstract

Abstract: The present research is oriented to characterize the physical and mechanical properties of the materials located in areas of non-metallic mining concessions of type quarry in the city of Loja, for conformation of subgrade materials of improvement, subbase and base, and so support a source of study applied to road infrastructure. This characterization was carried out in four stages, as first, determine the areas of the quarries of study, the second the sampling of each one of them for later analysis, the third lab work, through which the samples are analyzed with the following tests moisture content, Atterberg limits (LL, LP, IP), sieve analysis, resistance to abrasion, compaction and support capacity (CBR). The parameters obtained from each quarry were the dosed with aggregate of Malacatos river in the following proportions: 50 percent of river with 50 percent of quarry, 60 percent of river with 40 percent of quarry and 70 percent of river with 30 percent of quarry, to generate materials of best features, or improve the geotechnical properties according to the specifications recommended by the MTOP, for use in future projects of urban infrastructure road of the city.
