| 摘 要： | 为了快速检测评价沥青路面压实质量，结合佛山“一环”沥青路面施工，分析了PQI（Pavement Quality Indicator）检测沥青路面压实度的工作原理和标定方法，并进行了PQI法与钻芯法的对比，验证了PQI法的测试精度．据此采用PQI对下面层AC-25C试验路的压实度、横向压实质量及均匀性进行了快速检测评价．研究结果表明，PQI法具有快速、可靠、安全和无损的优点，可广泛应用于沥青路面施工过程的质量控制．

| Abstract: | In order to test and evaluate the compaction quality of asphalt pavement rapidly, the working principle and the calibration method of Pavement Quality Indicator （PQI） for the compactness testing in asphalt pavement is analysed in accordance with the construction of asphalt pavement in the First Loop Road of Foshan City. The testing precision of PQI is checked by the comparisons between the PQI and the drilled core method. The PQI is applied to rapidly test and evaluate the compactness,the transverse compaction qualit and the uniformity for the trial road with the subface AC-25C. The results show that the PQI method has the advantages of rapid speed, reliability, safety and nondestruction, and it can be widely used in the quality control of construction procedure in asphalt pavement. |
