摘　　要：应用PQI技术,依托实体工程,研究了碾压温度和碾压速度对沥青路面压实效果的影响。结果表明:(1)PQI路面密度快速测试方法应用可靠性较高;(2)采用PQI测试压实路面密度变化,可快速确定合理的碾压温度范围;(3)碾压速度过快会造成路面密度和压实度降低。施工时,碾压速度不宜照搬规范,建议采用PQI快速检测压实效果,确定合理的初压和复压速度。The effect of rolling temperature and rolling speed on asphalt pavement compaction is studied in this paper by PQI technology applied on entity engineering. The results show that： （ 1 ） the reliability of PQI pavement density quick test method is high; （2） By PQI test pavement compaction density changing, can quickly determine the reasonable rolling temperature range; （3） Rolling too fast will cause the reducing of road density and compaction degree. In construction, the rolling speed should not be easily determine by coping specification, PQI should be used to measure the compaction effect rapidly and determine a reasonable velocity of first compaction and second compaction.
