Abstract:

In order to obtain the interlayer strain condition of pavement and monitor the state of the road in real time, an automatic collection system of unattended interlayer strain signal was developed. A four-axle truck was selected for field test to analyze the characteristics of the collected strain signal, and the zero drift of the measured signal was eliminated by removing the trend term. The S variation method was used to study the distribution of interlayer strain signal in time and frequency domain. Finally, in order to improve the signal-to-noise ratio of measured road strain signals, low-pass filtering and wavelet filtering methods were used to preprocess the signals. The results showed that the developed system realized the automatic collection of road strain signal. The noise component frequency of the collected pavement interlayer strain signal was not fixed, and the effective component of the road strain signal was mainly the low-frequency signal below 50 Hz. The low-pass filtering method had limitations in processing strain signal, and wavelet filtering method was suitable for the pretreatment of strain signals between pavement layers for its great filtering effect on different types of noise signals.

Key words: pavement engineering, zero drift handling, wavelet-denoising, low-pass filter, signal processing
