摘要

在現行國道主管機關台灣區國道高速公路局之制度下，國道路面自竣工後須針對各路段進行巡查作業，而如何有效地提升國道巡查作業到表面損壞之養護及維修的程序之績效實為重要。為了進一步分析及擬訂具有效益之國道路面整修制度，本研究於國道高速公路全線進行相關試驗及檢測，並針對經常性整修路段進行結構分析，以提供國道養護及維修程序擬定之相關建議，為達成國道路面整修制度之提升。
國道高速公路自竣工後數年，由於環境、交通量、氣候等因素，往往於路面出現損壞之跡象。另外，由於現行國道皆已漸漸進入養護及維修之階段，對於國道鋪面之維修實乃高公局首要之任務。
緊急性修補之路段便可根據破壞類型，依據高速公路養護手冊進行緊急性之維修。而非緊急性修補之路段，便可透過透地雷達及落錘式撓度儀進行後續分析，以瞭解非緊急性修補之路段經常性整修之原因，以提出相關改善之建議。
本研究利用BAKFAA及Elmod撓度回算程式進行全國道高速公路共十段之經常性整修路段進行撓度回算分析，配合透地雷達、鑽心資料進行後續專案分析，以關西段、斗南段、新營段之經常性整修路段為例，進行專案分析。並將所完成之檢測及試驗資料，匯入台灣鋪面管理系統平台，以利後續工程師使用。
最後提出撓度分析、專案分析、系統建置之相關結論與建議。

Under the existing system of national road authorities in Taiwan Area National Freeway Bureau, freeway pavement need to be conducted a series of inspections operations for each section after the road is completed. Therefore, how to improve the efficiency of freeway inspected operation and the maintenance and rehabilitation procedure of pavement surface condition is a real important issue.
To analyze and find a efficient freeway pavement maintenance system, this study conducts a series of test and detection and executes pavement structure analysis in order to provide Taiwan Area National Freeway Bureau related proposals of planning maintenance and rehabilitation procedures, and then achieves the goal of improvement of maintenance system.
Due to the effect of environment, traffic and climate, national freeway pavement has some destructive conditions after it has completed. Moreover, national freeway has gradually arrived the stage of maintenance and rehabilitation, and so the maintenance and rehabilitation of the national freeway pavement becomes a most important mission for Taiwan Area National Freeway Bureau.
Emergency repaired road can be based on the type of pavement damage, according to highway maintenance manual to conduct a emergemcy repair. Non-emergency repaired road also can use ground-penetrating radar and falling weight deflectometer to conduct subsequent analysis in order to find out the reason of damage ,and then provides some related suggestions.
This study uses BAKFAA and Elmod to conduct deflection analysis of ten sections of usually repaired freeway pavements, and then uses GPR and FWD’s data to proceed subsequent analysis and uses Guanxi, Dounan, and Shinging district as examples to proceed project analysis, and then import the related data of detections and tests to Taiwan Pavement Management System to provide engineers to use. Finally, privode some related conclusions and suggestions of deflection analysis, project analysis, and deflection system.
