Compared with the traditional sampling quality detection method, the continuous compaction control technology has significant advantages in real time, full range and comprehensiveness. Therefore, this technology has gradually been widely used in the filling project. However, there are more than ten kinds of continuous compaction control methods, and the applicability of each method is different. Therefore, in order to promote the continuous application of continuous compaction control technology in China. The basic principles of various testing methods for continuous compaction control technology of filling engineering are summarized. The existing continuous compaction control technology testing methods are divided into four categories: (1) compaction method; (2) stiffness/modulus Method; (3) kinetic method; (4) energy method. The calculation process and supporting equipment of each detection method are introduced respectively. The applicability of various methods is analyzed based on the basic theory of various methods. The applicable scope and application suggestions of each detection method are proposed. The results show that the compaction method and energy method can be applied to fine-grained fillers, and the stiffness/modulus method and kinetic method can be applied to coarse-grained fillers and asphalt mixtures. According to the specific engineering conditions, the selection of suitable testing methods for continuous compaction control can obtain satisfactory application results.
