Identification of highway performance along with service life is very important. The complexity of highway pavement process design requires a better understanding related to physical parameter of the velocity-acceleration process of material caused by the traffic. Vibration monitoring was conducted by using an accelerometer sensor-based equipment. An accelerometer application as a vibration monitoring sensor is non-destructive testing of structural health monitoring system (SHMS). The purpose of this paper is to study the actual acceleration-velocity pavement dynamic behavior triggered by traffic load on the rigid pavement type. The testing was conducted by using a set of acceleration sensors installed on the pavement. All types of vehicle passes were recorded to find the understanding of the acceleration-velocity pavement dynamic behavior in real time. In this paper, the properties of acceleration-velocity were established and the important parameters including vehicle speed of vehicle and axle load, were defined. The results have shown that the acceleration-velocity pavement dynamic behavior was most affected by vehicle speed and the type of vehicle which related to axle load. Motorcycle with velocity 33.80 km/h has frequency 17.57 Hz and heavy vehicle has frequency 205.07 Hz with velocity 16.14 km/h. The results depicted that parameter dynamics of pavement have a positive correlation to the speed and axle loads. The acceleration magnitude for motorcycle, car and heavy vehicle are 30 cm/s2, 500 cm/s2, and 700 cm/s2 respectively. The factors of weight and speed of vehicles contribute to pavement vibration behavior. © 2024 by authors, all rights reserved.
