Abstract:	日本道路協會參考AASHTO鋪面現況服務能力指標(Present Serviceability Index，PSI)之建立模式，結合日本常見鋪面損壞形式，建立日本PSI。1980年代，日本建設省土木研究所以美國及日本之PSI，使用多元迴歸開發維護管理指標(Maintenance Control Index, MCI)，與傳統鋪面狀況指標(Pavement Condition Index, PCI)相比計算更為簡易。研究以中央大學與日本研究團隊共同開發的道路鋪面檢測車調查國道一號南下374.3車道公里，調查項目包含裂縫率、車轍深度及國際糙度指標(IRI)，探討MCI應用於臺灣高速公路鋪面調查之可行性。此外，研究蒐集ETC(Electronic Toll Collection)資料進行交通量分群，中位數檢定結果顯示不同養護工程分局轄區之交通量有差異，且MCI亦有差異，說明交通量為影響鋪面服務品質之因素之一，研究建議管理者於設定管理目標或門檻時應依據不同地區條件有所調整。因目前臺灣未建立MCI相關規範，故研究利用95%信心水準及日本首都高速公路MCI養護目標5.6評估國道一號鋪面現況，結果顯示達95%以上路段鋪面品質符合日本首都高速公路養護目標。最後，研究蒐集國道北區養護工程分局108年整修計畫資料與MCI調查結果比較，整修計畫路段中MCI小於5.6之路段占全轄區MCI小於5.6路段之71%。研究利用MCI0結果計算之移動平均可挑選出鋪面破壞較嚴重之路段，且與目前整修計畫所預計整修路段重合度高。綜合本研究成果，研究認為MCI能夠簡化臺灣高速公路鋪面調查作業，且能夠快速評估鋪面破壞情形，值得進一步研究與採用。;The Japanese PSI was set up by Japan Road Association by means of AASHTO Present Serviceability Index (PSI) as reference. In the 1980s, the Japan Institute of Civil Engineering set up the Maintenance Control Index (MCI) based on multiple regression, MCI made the roads easier to assess than Pavement Condition Index (PCI). This study collect the road conditions of National Freeway No. 1 section 374.3 km-lane south surveyed by vehicle. It is jointly developed by the National Central University and the Japanese research team. The vehicle is capable to survey cracks, rut and International Roughness Index (IRI). Taiwan Electronic Toll Collection (ETC) traffic data for National Freeway No. 1 was collected for clustering purpose. The median test showed that there are differences in traffic volume between freeway branch. MCI also showed the same result. So this study proposes that the authority should set various criteria or thresholds as depends on various conditions. This study used 95% confidence level and Japan Capital Expressway MCI Maintenance standard of 5.6 to evaluate the current freeway conditions of National Freeway No.1. The outcomes demonstrated that over 95% of the pavement quality meets the Japanese standard. The study also analyzed the 2019 renovation plan of the northern branch. The MCI survey found the freeway section with MCI less than 5.6 include 71% of the renovation plan. By using the moving average to select the worse section of highway. It is highly match to the current renovation plan. In summary, this study considered that MCI can simplify the freeway survey in Taiwan and rapidly evaluate the damage of pavements. It is worth to be used and further research.
