A grading parameter for evaluating the grading-dependence

Therefore, to better capture the grading-dependence of the shear stiffness, a new grading parameter considering the distribution of all the aggregates within a cubic sample was proposed. The grading parameter was found to increase with decreasing coefficient of uniformity and median particle size, where a higher shear stiffness was observed.
