摘要
针对高速公路低液限土的特点,采用不同冲击振动压路机组合工况进行试验,碾压后测量压实度评价低液限土的压实效果。研究表明:采用冲击压实技术能够达到低液限土的压实需求,比普通压路机的组合压实效果提高了5%左右,为工程应用提供了可靠依据。
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
