摘　　要：压实是沥青路面施工中最重要的工序,直接影响路面强度、刚度及稳定性,规范、准确地开展压实度检测至关重要。在普通国省干线改扩建项目中,交工验收质量检测时,路面压实度会出现一定幅度的提高。为了进一步验证此规律,选取宁夏境内两条公路,采集通车运营6个月及1年压实度数据,通过分析数据变化,得出压实度随时间的变化情况。Compaction is the most important process in asphalt pavement construction,which directly affects the strength,stiffness,and stability of the pavement.It is crucial to carry out standardized and accurate compaction testing.In ordinary national and provincial trunk road renovation and expansion projects,there will be a certain degree of improvement in road compaction during the quality inspection of handover acceptance.To further verify this pattern,two highways within Ningxia were selected and compaction data were collected for 6 months and 1 year of operation.By analyzing the changes in data,the variation of compaction over time was obtained.
