博士 === 國立中央大學 === 土木工程研究所 === 97 === Pavement construction is tightly related to the daily lives of those involved. However, for a long time, uneven pavements have been a pain in the heart of the Taiwanese people and road engineers. The causes of uneven pavements include the huge population travelling within the confined area of Taiwan, the uneven distribution of rainy seasons and the frequent reworking of pavements and roads for pipeline/cable construction and maintenance. Studies have also found issues with the limited capacity and frequent changes in human resources in labor departments of the government, which results in a discontinuous project experience in the roads authority. Moreover, due to the large amount of pavement maintenance work produced in recent years, the limited knowledge of young engineers in flexible pavement maintenance has led to difficulties in actual construction. Therefore, this study has systems thinking the level of pavement knowledge and established an interactive link among subjects in pavement knowledge, known as a "knowledge net". With positive analysis, inverse thinking and subject association in the knowledge net, commonality has been found in pavement maintenance issues that have been successfully simplified into two major departments and divided into three quantity evaluation thresholds. Four dispersed models are thereby further classified, providing a structure to the differential diagnosis method of flexible pavements. With the results from this assessment, we further develop two new techniques to solve existing issues concerning pavements. Finally, this study will establish a website to share knowledge about flexible pavements.
