Abstract: In order to continuously detect the compactness of asphalt mixture pavement in real time, the acceleration effective value in the process of vibration compaction was used as the main calculation parameter of the compactness of asphalt pavement. Based on Labview virtual instrument, a continuous testing system for vibration compaction was established, and the data of the measured acceleration in different periods were fitted and analyzed. The compactness data was compared with that obtained from field experiments. The results show that calculation of the effective value of acceleration within 0.4 seconds can be used as the main parameter of the pavement compactness of asphalt mixture, which provides a theoretical and scientific basis for the study of the continuous testing system for mixture vibration compaction.
