Research on the ICP Acceleration Sensors Detecting Roadbed Compaction Degree Test
Compaction is an important influencing factor that makes various structural materials of road embankment and surface sufficiently dense, and it becomes more and more important that effective detecting methods of the compaction degree are employed to monitor the quality of compaction. In this paper, the testing methods and means that the compaction degree of sub grade soils was detected by the acceleration sensors during the compaction process of vibratory roller were presented, with which the field tests were performed to measure the acceleration of vibratory drum of the vibratory roller and the compaction degree of compacted soils, and then the relational expression between the vibratory acceleration and the compaction degree of soils were obtained. Results indicate that there exists such a significant positive correlation relationship between the virtual value of vibration acceleration and the soil compaction degree that the former can be used to characterize the latter accurately. Therefore, it provides a technical support for the development of nondestructive and live vibratory roller compaction degree detection technology.
