摘　　要：为研究沥青路面压实质量快速检测中PFWD应用的要点,以指导工程实践,依据PFWD快速检测理论和原理,采用了实例分析方法,研究了临离高速公路中一城市道路段半刚性基层、沥青面层压实质量快速检测要点以及检测结果的龄期和温度修正思路,并给出了PFWD荷载传感器和位移传感器系统性能稳定,能持续用于施工现场质量监测与验收以及PFWD反算模量和路基路面压实度之间存在较好函数关系。In order to study the key points of PFWD application in rapid testing of asphalt pavement compaction quality and guide engineering practice,according to the theory and principle of PFWD rapid testing,the case analysis method is adopted to study the key points of rapid testing of semi-rigid base of urban road section and asphalt surface layer compaction quality of the Linli Expressway,as well as the idea of age and temperature correction of test results.It is concluded that PFWD load sensor and displacement sensor system have stable performance and can be used continuously for quality monitoring and acceptance of construction site,and that there is a good functional relationship between PFWD inverse modulus and roadbed and pavement compaction.
