本文旨在對非破壞性撓度試驗之穩態撓度試驗（Steady-state deflectiontest）與衝擊撓度試驗（Impact deflection test），建立以動力分析為基礎，且符合國內高速公路鋪面狀況之撓度指標評估表，提供公路養護單位快速簡便的鋪面定性評估方法。研究結果顯示，運用動力分析架構而成之撓度指標評估表，除能概括現階段以經驗架構而成的撓度指標法外，其更能有效地監控鋪面加鋪前後之結構改善，所評估之鋪面結構狀況並與動態回算分析結果具有相當的一致性。 This study is to propose a new Deflection Index estimation based ondynamic stress analysis and pavement conditions of domestic highway tomeet the needs of steady-state deflection test (Road Rater) as well asimpact deflection test (FWD). The estimation can offer highwaymaintainer agencies convenient procedures in determining the pavementstructural capacity. Result shows that the new Deflection Index Methodcan yield compatible results with those founded empirically. Theefficiency of the method is indicated in supervising the pavementbefore and after the overlay. In addition, the pavement evaluation hasconsistency with the out come of dynamic backcalculation analysis.
