Correlación entre el CBR, DCP, propiedades índice y mecánicas en suelos, de las parroquias Rumipamba y Yanayacu del cantón Quero

Abstract

In this job 3 roads were selected for per parish and two wells on each road, by performing a total of 12 wells in which field tests and sample extraction for laboratory tests. Tests were conducted on: Field Density (Ottawa Cone and Sand), Dynamic Cone Penetrometer (DCP), Granulometry, Atterberg Limits, Specific Gravity, Compaction (Modified Proctor) and California Bearing Ratio (CBR). After the field and laboratory tests were completed, the analysis and interpretation of results and the elaboration of correlations using simple regressions and by the method of least squares were carried out. In which a total of 30 correlations with a correlation coefficient greater than 50.3 percent were obtained, so the correlations are acceptable. Finally, a flexible pavement was designed with both the CBR obtained in the laboratory, as well as the CBR obtained by correlations, noting that there was no major change in the design of the same, since the final design was asphaltic layer=10cm, base=10cm and sub-base=15cm for both cases.
