Identification of Asphalt Pavement Surface Cracking Based on Vehicle Vibration Analysis
The surface cracking condition of asphalt pavement affects the service life of pavement struc-ture.It is very important for the maintenance intervention to realize the rapid and accurate identifica-tion of pavement cracking.Vehicle vibration-based method is emerging with the advantages of fast,low cost and real-time feedback.Based on the independently developed multi-point vehicle vibration testing system,the vibration signal samples collected from on-site experiments were divided into two sets,pavement cracking and distraction objects.Time domain analysis,response time analysis,and probability density analysis were carried out to conclude their features and difference.It can be seen that the response time and probability density peak can effectively distinguish between pavement dis-tress and distraction objects.The research results can be used for the identification of asphalt pave-ment cracking.
