摘　　要：临海高等级公路沿线土质普遍为粉土或粉土夹粉质黏土。当该土质作为底基层材料时,采用水泥石灰综合稳定较单一采用石灰稳定具有早期强度高、板体性好、表面不易松散等优势,但在足够的压实功作用下,压实度始终不能满足要求。通过大量的试验和现场检测,对压实标准做了研究和探讨,并与石灰稳定粉土进行综合比较,提出较为合理的解决压实度不足问题的方案。It is found that soil along the coastal highway present high quality of silt. When the soil is used as the sub-base, which stabled by cement-lime would obtain higher strength and be better formed compared to that stabled by lime. But the compaction degree could not be satisfied. A great deal of experi- ments and field detections are done to research the compaction standard. Comparing with the lime stabi- lized sub-base, effected measures are presented which are useful to control the compaction.
