- Abstract:
-
Based on the ultrasonic theory,the ultrasonic reflection method was suggested in the paper as nondestructive testing for steel bridge deck pavement layer bonding strength.According to five kinds of common interfaces in practical engineering,three types of related samples were made,and many detection tests were done by using the ZBL-520 non-metallic ultrasound instrument.By studying the waveform and acoustic parameters of each interface,it was found that the amplitude value could be used as the physical quantity to detect the bonding strength.Finally,the comparative experiments of loss and lossless interfaces were carried out on the same sample.The test results indicated that there were different degrees of differences in the amplitude of each interface,and the good bonding interface’s relative amplitude value was the smallest.The quality of bond layer of a part or the total of a bridge could be judged by the average value of a large number of measured point data.
