摘要

平坦度驗收為路面鋪築過程中重要的一環，台灣大學團隊於民國九十六年已提出慣性式平坦儀之標準驗證程序及方法制定，並公布於國家標準CNS 15317「鋪面量測用慣性剖面儀驗證法」。雖然使用慣性式剖面儀進行路面平坦度評估與驗收工作已成為各國之現況或未來必然趨勢，然而在我國慣性式剖面儀的使用仍需更積極的推廣，目前國內道路主管機關頒布之新工道路或養護檢測規範主要仍以高低平坦儀等直規式儀器作驗收。然而國內外近乎沒有關於此類儀器的相關規範，各單位在使用上標準分歧，容易因可靠度及可信度不足而引發廠商爭議。
有鑑於此，為高低平坦儀訂定一套標準的驗證方法以及交叉比對相關性的門檻值以供日後單位有統一的準則可以參考為本研究的首要目標。本研究首先透過相關文獻回顧與高低平坦儀問卷調查及訪談、研擬電子式與機械式高低平坦儀驗證方法，接著透過實地於室內以及台灣大學竹北校區試做驗證方法並不斷加以修改，最後提出標準驗證方法以及儀器之重現性及準確性分級門檻值訂定。希望本研究藉此能提升高低平坦儀驗收的可靠度，強化操作人員之正確認知與專業知識，並有助於提升國內道路鋪面平坦度之檢測品質。

The flatness acceptance is an important part of the paving process, National Taiwan University team has made in the Republic of 2007 inertial flat instrument standard verification procedures and methods to develop and publish national standards CNS 15317 "pavement measured inertial profile instrument validation. Although the use of inertial profile instrument road surface flatness evaluation and acceptance of work has become the current situation in any country or the future of an inevitable trend, however, in the promotion of the use of China's inertia profile instrument of still more positive of, the current domestic road competent authority the promulgation of the new work Road still the level of the flat and other direct regulatory instrument for acceptance or maintenance test specifications. However, at home and abroad almost no relevant norms on such devices, each unit differences in the use of standard, easy due to the lack of reliability and credibility arising from the vendor dispute.
For this reason, the level of flat instrument to a set of standard authentication methods, as well as cross-correlation threshold for future units of uniform criteria can refer to the primary goal of this study. In this study, through literature review and questionnaire survey and interviews with high and low flat instrument, to develop the validation method of electronic and mechanical level of flat instrument, and then through the field in the indoor and National Taiwan University campus Jhubei try to verify and continue to be modified, Finally, the standard authentication method and instrument reproducibility and accuracy of the classification threshold is set. I hope to take this research can improve the reliability of the level of acceptance of a flat instrument to strengthen the correct understanding of the operating personnel with professional knowledge, and help to improve the quality of the detection of flat road pavement.
