Prof. Zhen Leng visited Department ofCivil Engineering, Tsinghua University on October 16th, 2018, andgave a lecture -“Nondestructive Testing of Transportation Infrastructure UsingGround Penetrating Radar: Theory and Practice.” About 20 faculties and graduate students participated the lecture.
At the beginning, Dr.Qinyan Xing, the hostess of the meeting, introduced Prof. Zhen Leng, who is the Director of the Hong Kong Road Research Laboratoryat the Hong Kong Polytechnic University.
Prof. Zhen Leng started with a briefintroduction of the Hong Kong Polytechnic University. He first introduced thesystem components and working mechanism of GPR. Then Prof. Zhen Leng presented itspractical applications in pavement layer thickness measurement, in-situ asphaltpavement density monitoring, and railroad ballast fouling detection. Inthe end, both the advantages and limitations of using GPR as a nondestructivetool were discussed.
All participants really enjoyed Prof. ZhenLeng‘s talk, and had a hot discussion on the topic after the presentation.
