| dc.description.abstract | Soils are the oldest and most complex engineering materials. The California Bearing Ratio (CBR) has been acknowledged as an important parameter to characterize the bearing capacity of earth structures, such as earth dams, road embankments, airport runways, bridge abutments and pavements. This research presents and discusses the results from a study on the prediction of CBR. In the current study, CBR testswere performed on thirty one samples of fine-grained soils in the laboratory, collected from various locations in Sululta Town. Based on the test results, the soils are categorized in to red clay and black/gray clay soils and the correlationswere done independently for the two categories. Then various linear relationships between index properties and CBR of the samples were investigated using simple and multiple linear regression analysis, predictive equation estimating CBR from the experimental index values were developed by multiple linear regression analysis and alesser empirical correlation was found with a correlation coefficient R 2 = 0.319for Red clay and satisfactory empirical correlation was obtained with a correlation coefficient R 2 =0.720for black/gray clay of the experimental soils. The equations are developed by using SPSS 23 for windows software. The equations are then tested for two control samples for the two categories. The most important equations are proposed, and applicable with sufficient accuracy for preliminary identification of material for the local area. | en_US |
