The dense-framework type of base-course's coarse aggregate proportion which provides in view of our country (China) standard is oversized, the fine aggregate between the expected content are relatively few, compaction on-site construction to meet standards is rather difficult, and indoor formation is subject to easy segregation. Using embedded and crowded filling method of grading the stone skeleton structure is proposed to obtain the new design gradation method and the scope. Based on the physical CBR and wheel tracking tests, the three methods, namely, dense-suspended type of norms, dense-framework type of norms and the new design method have been evaluated for comparative study. The experimental study results indicated that embedded and crowded filling method of graded granular produces good mechanical properties and easier for on-site construction.
