Abstract
Automated Pavement Distress Detection System (APDDS) has been a useful tool for pavement management in the world. APDDS can evaluate pavement performance and make maintenance and reconstruction（M&R）decisions based on distress and roughness data, it. In Taiwan, road authorities use pavement condition indices to evaluate pavement condition. However, insufficient labor and budget cause inefficient management works. Therefore, using efficient way to manage pavement performance is an important issue in the future.his study investigates several flexible pavement sections and collects automated/manual pavement distress data according to experiment design. Further, the data are analyzed and compared. It was found that the data collected by APDDS are undesirable due to frequent patches and other inferences. However, this study found that the ability of detecting cracks in PicCrack could be improved by spraying water on flexible pavement. In addition, this study discussed the differences of automatically/manually-collected survey results.his study analyzes the total time needed in semi-automated and manual survey. The results show that in all sections the total time needed in semi-automated survey (average 36.49 minutes) is longer than the total time needed in manual survey (average 13.03 minutes). This phenomenon indicates that using APDDS to collect image data takes more time because the surveyors have to go through the data and note down distresses. However, using APDDS can obviously reduce the time and labor during field survey. Moreover, manual field survey is easily affected by complex traffic condition in Taiwan. Therefore, by using APDDS, road data could be obtained quickly and the safely of surveyor could be protected.
