system. A mixture is considered to be coarse-graded if the gradation band passes below
the restricted zone. Conversely, a gradation band for a fine-graded mixture passes above
the restricted zone. Hence, the two different graded subsets to be tested are as follows:
* Coarse-Graded Mixtures,
* Fine-Graded Mixtures.
Tables 5-7 and 5-8 list the coarse- and fine-graded mixtures and their categories,
respectively.

Table 5-9 shows the correlation analysis results for the Course Graded mixtures. A
zero-order bivariate correlation study found no statistically significant relationship
between nca, nfa, and |E40*|. However, considering the small sample size (N = 7), Table
5-9 shows that a strong negative correlation exists between nfa and |E40o*
