0引言压实度是沥青路面施工质量管理中最为重要的指标之一。压实度的大小取决于现场实测的沥青路面密度。目前,列入中国行业规程的沥青路面密度(压实度)检测方法有三种:钻芯法、核子密湿度仪法、无核密度仪法。三种方法各有所长,适用于不同的检测需求。1现行路面密度检测技术对比 0 Introduction Compaction is one of the most important indicators of asphalt pavement construction quality management. The degree of compaction depends on the field measured asphalt pavement density. At present, there are three methods for testing asphalt pavement density (degree of compaction) included in China’s industrial codes: drill core method, nuclear density meter, nuclear-free density meter method. The three methods have their own strengths, suitable for different testing needs. 1 current road surface density testing technology comparison
