| Abstract: | According to the characteristics of low liquid limit soil, different combination conditions of impact vi- bratory roller were tested. After compaction, the degree of compaction was measured to evaluate the compaction effect of low liquid limit soil. The results show that impact compaction technology can meet the requirement, and the degree of compaction increases by 5 percent than the combination of normal rollers. It could provide basis for encllneering application |
