Prediction of Soaked CBR Value With Index Properties of Black Cotton Soils of Sangareddy Region

Prediction of California Bearing Ratio from Consistency and Compaction Characteristics of Fine-grained Soils

“…In those studies, it is concluded that the CBR and liquid limit correlations are relatively negative, in addition to prediction of the real CBR value, the limit cannot be utilized. In contrast, the result of Prashanth et al [21], and Mishra and Tegar [16] were higher compare with the result of this study. Those studies outcomes were proved by depending on mathematical modeling through using practically-determined CBR value.…”

“…This study result is larger than the result obtained in the study of Roy [23], Bassey et al [7], Priya et al [31], and Torgano et al [30], negative correlations between plasticity index and CBR was observed. The present study outcome is less than the achieved result by Prashanth et al [21], Mishra and Tegar [16], which were achieved R 2 values of 0.757 and 0.934, respectively. The variation of PI with CBR values as a single variable shown in Figure 3.…”

“…3 (see Table 3 for statistical parameters) was 0.5192, which is above 50% implies that a notable correlation between independent and dependent variables in this study. This achievement agrees with the achieved results in the studies of Prashanth et al [21], Mishra and Tegar [16], Gudeta and Patel [11], and Priya et al [31]. However, several studies' outcomes showed that the relationship by utilizing plasticity index parameter cannot be accurately used to predict the values of soaked CBR (Roy [23], Bassey et al [7], and Torgano et al [30]).…”

“…A negative correlation by several studies (Bassey et al [7], Farias et al [10], Torgano et al [30] and Priya et al [31]) was found for OMC and CBR values, and OMC cannot be utilized accurately in the prediction of the CBR value, which disagrees with the outcomes of the current study. The results of this study were compiled with the achievements of several studies such as Lakshmi et al [14], Prashanth et al [21], Roy [23], Mishra, and Tegar [16].…”

“…The prediction of CBR of fine-grained soil as a function of Soil's consistency properties was considered in many studies such as Talukdar [29], and Saklecha et al [25], Roy [23], Bassey et al [7], Farias et al [10], and Torgano et al [35], their results reveal that correlations of CBR with LL, PL, and PI as a single variable were concluded to be relatively negative in the prediction of the real CBR value cannot be from those limits. However, good correlations for prediction of CBR value from LL, PL, PI, OMC, and MDD with as a single variable equation were achieved by Kumar et al [13], Prashanth et al [21], Gudeta and Patel [11], Mishra and Tegar [16], Priya et al [31], and Katte et al [12]. Moreover, various indx parameters such as specific gravity (G), coefficient of uniformity (Cu), coefficient of curvature (Cc), liquid limit (LL), plastic limit (PL), plasticity index (PI), optimum moisture content (OMC) and maximum dry density (MDD) for alluvial soil were correlated with CBR in the study of Alam et al [1].…”
