碩士 === 國立中央大學 === 地球物理研究所 === 90 === This study is aimed at using Ground Penetrating Radar (GPR) to analyze concrete pavement structure and map the rabars under pavements. Using a three-dimensional (3-D) GPR presentation to map the pavements is also included. Due to manipulate GPR system takes time and increases costs, mounting GPR on power-steering wheelchair and/or automobile makes the survey quick and easy. Testing surveys were carried out at four toll stations, namely Ming-jian, Shann-huah, Bair-her and Guu-keng respectively, along the Secondary Southern Freeway and runway in Tainan airport. The thickness and variability of the pavement layer can be mapped.
