摘要To understand the influence of formation methods on the performance of graded gravel,graded gravel specimens composed through two common methods, i.e., compaction and vibratory formation, were analyzed. First, the K change method was adopted to design the graded gravel; subsequently, the graded gravel specimens were generated through the aforementioned methods. The maximum dry density, optimum moisture content, and CBR values of the specimens were measured separately, and the parameters were analyzed comprehensively. The analysis of the ideal data indicated that (1) compaction formation severely disturbed the previous gradation of graded gravel, particularly the gradations from 13.2 mm to 1.18 mm; that (2) vibratory formation slightly disrupted but basically maintained the previous gradation; that (3) the CBR values of the graded gravel specimens formed through vibratory formation were almost twice as high as those generated through compaction formation; and that (4) a densely graded gravel specimen does not indicate a high CBR value.
