    Abstract: 本文針對非破壞性撓度試驗之穩態撓度與衝擊撓度試驗,以動力分析為基礎,建立符合台灣地區柔性鋪面狀況之撓度指標評估表。該評估表除能概括一般由經驗與統計架構而設立之撓度指標法則外,其對鋪面各層材料狀況的掌握將更為詳盡。由分析實驗顯示,該撓度指標可監控道路加鋪之結構改善,並說明結構體的弱層;其評估結果亦與動力回算相似,兩者合併運用將使撓度法應用更為確實。
    New deflection indices representing for the qualitative structural capacity of flexible pavements are studied with dynamic stress analysis for steady state and impulsive nondestructive deflection tests on pavements. It is found that the layer condition can be verified more accurately from this suggestion than conventional ones. With the verifications on experimental deflections, rehabilitation efficiency of overlay construction is revealed, and the weak layer is shown effectively. Similar pavement conditions are predictable from the dynamic back-calculations. Incorporating both methods shall enhance the deflection tests in practice.
