Caracterización de los materiales de subrasante en zonas no urbanizadas de la ciudad de Loja, aplicadas a obras de infraestructura vial en el polígono denominado-Chonta Cruz

Abstract

Abstract: This paper aims to characterize the subgrade materials applied to road infrastructure and the creation of the geotechnical zoning maps of the polygon called Chonta Cruz, depending on soil classification and soil bearing capacity for which use was made of the GIS software. To the obtaining the samples for study, it was performed, information gathering, field visit, delimitation of the study area, identification and location of the respective study points spaced approximately 500m each other, it was performed the making exploration of the soil at three depths 0.5 m, 1.0m and 1.5m. For the study of the physical-mechanical properties of the material the following laboratory tests were performed:moisture content, Atterberg limits, particle size analysis, modified proctor, CBR (California bearing ratio), abrasion test, and in situ as DCP (Dynamic Cone Penetrometer), and pocket penetrometer, for then make a correlation of results with the CBR.
