摘要本文針對非破壞性撓度試驗之穩態撓度與衝擊撓度試驗,以動態應力分析為基礎,建立符合台灣地區柔性鋪面狀況之撓度指標評估表,供鋪面定性評估使用。該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確實。由分析實驗顯示,撓度指標法可有效地監控道路加鋪之結構改善,並說明結構體的弱層;若忽略岩盤及各層厚度之影響,其評估結果將與動力回算相似,兩者結合運用將使撓度試驗法應用性更為落實。;Based on dynamic analysis of steady-state and impulsive nondestructive deflection tests on pavement, new deflection indexes representing for the qualitative structural capacity of flexible pavements in Taiwan are suggested in this study. As the result of statistics analysis, the newly developed indexes are more generalized than the conventional ones. Layer conditions can be verified more accurately by using this method. By comparing with the dynamic backcalculations on experimental deflections, rehabilitation efficiency of the overlay construction is revealed; the weak layer of the structure is effectively shown. Neglecting the influences from bedrock and layer thickness, similar pavement conditions can be interpreted by dynamic backcalculation and this method. Incorporation of both methods shall make deflection tests more applicable in engineering practice.
