Abstract: Empirical approaches based on construction experience and drilling cores are always used to evaluate compaction techniques of superpave,which are not satisfactory because of their poor efficiency,few data or poor consistency.Pavement Quality Indicator (PQI) is introduced,a non-destructive monitor device,which can obtain a great deal of air void data of asphalt pavement fast.It is proven that PQI can evaluate compaction techniques soundly and roundly.

Key words: superpave, PQI (Pavement Quality Indicator), air void, compaction techniques

摘要： 为了评价沥青路面压实工艺的优劣,以往主要依靠施工经验和钻芯取样法检测路面压实度来分析,由于效率低、数据量少、代表性不强而常常不如人意。沥青路面质量指示仪(PQI)是一种无损检测设备,可以快速、大量地获得路面空隙率数据。实践证明,PQI可以科学、全面地评价压实工艺的优劣。
