Abstract
This paper aims to analyze the influence of physical parameters of asphalt pavement on ultrasonic waves and tries to establish the relationship between physical and acoustic parameters. Among them, physical parameters include the density, elasticity modulus, viscosity, and incident frequency. Acoustic parameters consist of amplitude, frequency, and attention rate. Based on finite element software COMSOL, both mechanical and acoustic models were established to simulate ultrasonic propagation in asphalt pavement. Through time and frequency domain, it was found that with the increase of distance, amplitude has an exponential reduction. Meanwhile elasticity modulus and viscosity had a high sensitivity to acoustic parameters, and others were weak.
