Abstract: Access database was used to establish a data table of the correlation between the compaction degree and the vibration acceleration under several factors. Combined with the LabVIEW virtual instrument software, the database management system of highway subgrade compaction was developed, which could retrieve and analyze the collected data more quickly. Meanwhile, a real-time analysis system of continuous detection for compaction degree was set up, which could realize the real-time call of relation formula in database, the processing and displaying of the collected signals.
