本研究目標為以透地雷達分析剛性鋪面厚度及鑑別鋪面內部之鋼筋，並探討以三維顯像方式應用於鋪面檢測之可行性。 由於傳統以人工施測之方式費時又費工。因此改以電動代步車和汽車來進行測試，並與人工施測結果比對，在不影響精度要求下求得較好的施測方式。並在南二高名間、善化、白河及古坑四個收費站區及台南航空站跑道，進行實地施測，以驗證車載透地雷達在剛性鋪面施測的效果。 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.
