STATISTICAL ANALYSIS ON PERMEABLE DEFORMATION TYPE OF CONTINUOUS GRADATION CRUSHED GRAVEL WITH H/F DISCRIMINATION METHOD

H/F discrimination method is used to discriminate the permeable deformation type of crushed gravel with continuous gradation. In order to verify its suitability by a testing method, the permeable deformation testing results are analyzed statistically for 92 samples from 28 projects. The results indicate that the coincidence rate is up to 87.0by comparing the discrimination results of permeable deformation type of continuous gradation crushed gravel through H/F discrimination method and testing results. It shows that the H/F discrimination method is applicable to the continuous gradation crushed gravel.
