The simulation experiment of the vehicle action on pavement was carried on. In the progress of the experiment, HZ-MS48 microseismic monitoring system was used to collect microseismic waves. And these microseismic signals were disposed and analyzed. It introduced the scheme and the process of the data collecting experiment. After that, several types of microseismic waveform were compared and discussed. Also shock waves for transmitting characteristic in pavement base were studied. At the same time, taking a typical microseismic event location as a case, the precision of microseismic event location was confirmed, which put forward a new way for monitoring traffic vehicles.
