摘要

鋪面平坦度一直都是路權單位與用路人所關切之課題。除施工技術與材料外，如何以準確且符合用路人實際感受之驗收方式，確保鋪面完工後之初始平坦度，將為影響其使用年限與行車舒適度之關鍵。隨著科技進步，以慣性剖面儀辦理驗收已廣泛應用於國際間，但國內仍因對其檢測數據存有疑慮而無法推廣。為此，本研究依據CNS 15371之規定確認慣性剖面儀檢測數據之重複性與準確度，並建立以慣性剖面儀檢測數據模擬計算高低平坦儀量測指標之演算流程；再將透過演算流程所得之模擬值，與高低平坦儀實際數據進行比對，證實慣性剖面儀取代高低平坦儀之可行性。

Pavement roughness is always the concerned issue for road agencies and road users. Besides the construction technology and materials, applying the appropriate and accurate measuring methods for acceptance test could ensure the initial roughness of pavement and also be the key factor of pavement life and riding quality. With the development of technology, utilizing the inertial profiler to execute the acceptance test is widely applied all over the world, but it is hard to generalize in Taiwan due to the doubt of measuring data. This study first verified the repeatability and accuracy of the data from inertial profiler by CNS 15371 and then developed a procedure of simulating the index of hi-lo detector from inertial profiler data to confirm its accuracy and applicability in actual pavement roughness acceptance by real data from road test. Finally, the feasibility of replacing hi-lo detector by inertial profiler was proved.
