Abstract The compaction quality of rock-fill structure was difficult to detect and evaluate. Based on the statistical analysis principles，the rock-fill particles water retention characteristics，relative density representative value and the maximum dry density were detected，and the detection method was formed to detect the physical state of compacted rock-fill road engineering. Both the float-down method and the representative specific gravity method were utilized to evaluate the granular volume rate. Supplemented detecting the outliers compaction，the effectiveness of the compaction quality evaluated by the granular volume rate was improved. At the same time，the misjudgment caused by the rock-fill particles adverse individual was avoided. The engineering example shows that the evaluation rationality and the operation of the rock-fill physical state by the proposed method are improved. The results may provide references for similar engineering projects.
